lightroom export reapplies history since import step

I'm using Lightroom Classic CC 8.1 on a windows 10 PC.
A friend recently gave me a batch of about 150 jpegs to process in Lightroom for him. So I imported them and tweaked the color balance exposure and contrast ect and cropped them. The I exported the to a new folder to have them as modified. They look fine in the new folder. However, when I view them in LR now it appears that all the steps in the history panel have been reapplied again making them over contrasty. Also the crop I applied has dropped to the bottom of the original photo so the top of the photo is cropped off! It's really weird.
To resolve it I have to select the import step in the history panel and them they look like the image I modified before I exported them.  This has never happened to me me before. I usually edit DNG files, these are jegs.
I don't understand what went wrong and don't want it to happen again as it took a couple of hours to fix. Has anyone got any ideas please?

What do you mean by "when I view them in LR now"

Looks to me like you replaced the original files by the exported JPEGs in the same location.
So now LR, thinking it is working on the original file, is showing you all your edits but on the wrong file.

Did you export (with same name) to the original folder (or move them there after export) overwriting the original files?
When you do this with DNG, LR will recognize that development metadata is not in sync with your catalog.
Not sure if that applies to JPEGs as well ...

Sounds indeed like you have overwritten the original jpeg files with the exported files. Or that you used 'Update Folder Location' in Lightroom to point Lightroom to the exported images. That means that Lightroom is using the exported images as originals now, and so your edits are shown twice: once because they have been 'baked in' the exported files, and once because Lightroom shows its edits.

If you want to view exported images in Lightroom, then you have to import them as if they are new images. There is even a checkbox in the export dialog to do that automatically.

Thank you very much gentlemen for your prompt and precise replies. I think you've hit the nail on the head. I exported the file to the same folder and LR gave them a unique name. I wanted to keep the original name so deleted the original files and renamed the unique names back to the original. So your explanations are spot on. Silly me! thanks so much for your help and I'll be more careful in future.
