Lightroom: If I use CC and classic together, are they using one catalog?

I seem to have a few different catalogs when I open Lightroom CC or Lightroom CC Classic. There are 5 different versions of a catalog with a -2 after the name for Classic. When I add new photos to CC, I cannot see them in Classic. Is my catalog supposed to be only one catalog? Or are they designed to use different catalogs?

You may have fallen into a loop with the update. Lr Classic will take your catalog and update it for use with the new program and add a -2 to the end of the name. If you accidentally open the older catalog again the process will repeat. This is possible because the original one is left in place.

The catalogs are in the Pictures/Lightroom folder...check in there and make sure you know which one is the latest and the one you want.

Then in the program, you can tell Lr to open that catalog specifically. You do that in the Preferences General Tab. Hope that helps.

I would also add; as a guide in deleting unwanted files, open the "most recent" catalogue. Make sure it's the most recent. Then while it's open, go to explorer/ finder where the catalogue is stored and delete every file that doesn't have the same name as the one that's locked(.lrcat.lock). In the example below, there are two catalogues stored here. The one that is opened(fist of the two highlighted) is 03 Property.lrcat because as you can see, it's the same one that is locked(03 Property.lrcat.lock) so I would be deleting the one the red arrow is pointing to and all associated files i.e. 03 Property.lrcat-2.lrcat, 03 Property.lrcat-2.lrcat-schm(if it exist), 03 Property.lrcat-2.lrcat-wal(if it exist) etc. As a general rule-of-thumb, the most recent(newest) catalogue would have the oldest number at the end(as per Steve's suggestion). In my example, this is 03 Property.lrcat-2.lrcat. In some cases, you may have "03 Property.lrcat-3.lrcat", "03 Property.lrcat-4.lrcat" etc

Lightroom CC and Lightroom Classic use separate catalogs. If you add an image to Lightroom CC, you need Lightroom mobile sync enabled in Classic for it to sync to the Lightroom cloud and pull down its copy of the original file.
