Lightroom doubles folders that are on my external harddrive - Lightroom wants to reimport when synchronizing

Hi, I have a very concerning problem with Lightroom Classic CC on my iMac. I noticed that Lightroom created a double folder from a folder (there is only one real folder with that name on my external hard drive WD Mybook). Then there are two folders with exactly the same name within Lightroom. Some photos (majority) are in one folder and some photos (minority) in the other folder. When I try to sync the folder Lightroom wants to remove and reimport all photos. Can anyone help my how to fix this issue?

Thanks for your help.

I could be wrong, but my first guess is that this is a variation of the duplicate-folder/capitalization problem I've been suffering for 2 years: https://feedback.photoshop.com/photoshop_family/topics/lightroom-2015-9-creates-strange-duplicate-ve...

It is a variation of the capitalization bug: https://forums.adobe.com/message/9354068#9354068

Every time I get it I have to go through the fix outlined here in comment #4: https://forums.adobe.com/thread/1167904

I have to jump through this hoop this every time I create HDRs or panoramas or, sometimes, sync photos from Lightroom on my phone. Often I have to quite and restart Lightroom before the reintegration of the folders will succeed without throwing an error, too.

Here's a screenshot of what just happened to me when I synced up some mobile shots from my phones. Not quite what you have but maybe of the same root cause. Note that there are two 2018-10-19 folders. On my actual hard drive, all the photos are actually in the same folder of that name.

The fix should be a one-time deal unless the path keeps changing. We could investigate further.

Actually it is not a real one-time deal. The fix (Jim Wilde) helps but is very time consuming cause you have to do the fix on every single folder. For example you have a mainfolder 2017 with 20 subfolders (some of them got screwed up by capitalization, some not). It doesn ́t help to do the fix with the 2017 folder but you have to do it with every screwed up subfolder :-( 

PS: in my case actually there were no differences in capitalization but I noticed that every folder with an ü/ä/ö letters was screwed up.

If it's the capitalization issue, the Jim Wilde fix (which I created in the first place when I first saw this issue some years ago) should be able to be done on a single parent folder and shouldn't need doing again unless the capitalization in the path changes. It's most frequently caused by a username case changing when moving computers, or by 

This sounds like a variation on the capitalization issue, since it's happening with certain characters instead of capitals, and could be worth researching further. Or you could avoid it by sticking to basic alpha numeric characters.

It seems that the already known CAPITALIZATION problem was the case even though there were no obvious differences between both shown folders (hovering). But Jim Wilde ́s workaround helped anyways. Thanks Stephan and Jim and I hope Adobe will finally solve this problem in general.

@admins: I couldn't find a way to remove my two screenshots above. Can you please remove them since there are quite a few personal infos that I don't like to be visible on the internet. Thanks!

This definitely sounds like the capitalisation problem. We all agree how you can fix this pretty easily, but I disagree that this is always a one time fix. It’s like taking an aspirine against a headache. If solves the acute problem, but it may not cure the underlying cause, because we often don’t really know the underlying cause. We know what happens, but we don’t always know why.
