The ongoing subscription updates should automatically import all your existing images from the old and current LRCAT file into the newly created LRCAT file. Either something is wrong, or the edits you're 'missing' were not in the current LRCAT file at the time of the software update such that they were not automatically migrated into the new LRCAT file.

You probably should do some LRCAT maintenance, getting all your images consolidated so this issue is either resolved or positioned for detailed investigation at your next software update. Therefore, consider the following steps:

1. Generate a list of the names and modification dates of all LRCAT files you now have in your \Lightroom folder.

2. Determine your current and active LRCAT file.

3. Consider exiting from the LR software and renaming that current LRCAT file to a clear identification name as an 'identifier' of which file is the 'master' as of March-2022, example" Lightroom Catalog-v11-Mar-2022.LRCAT".

4. Then, merge the contents from your 'work list' created in step one into this master / current LRCAT. You can simply double-click the 'master' LRCAT file to have the LR software open with that file as the current catalog. Then, use: File / Import from another Catalog. Navigate to the first and oldest-mod-date LRCAT from your list and select that LRCAT as the import "source". The LR software will analyze the source catalog and give you an option to import just the missing images or to stack (virtual copy) existing images over the same images in your current LRCAT. Assuming all your images are in their 'proper' position on disk, just import the Develop settings and metadata without moving any image files. When processed, check-off that file from your work-list and continue with the next candidate LRCAT.

5. When all the LRCAT files are processed / merged, move those older LRCAT files to your back-up storage, in case you ever need to revisit. But technically, all those files are now merged into your single master / current LRCAT, and the old LRCAT files are now redundant. You'll have them on your recovery media, but never should need them again.

6. When the next major LR update occurs, Adobe will likely add a new version number into the new LRCAT file. It should be easy to recognize that software update from how it adds maybe a v12 to your Mar-2022 name at some future date, maybe 2023. But, all the merge data should automatically move into that new LRCAT file. If not, you have an opportunity to discuss with Adobe technical support that obvious issue, at that future date, based on two easy to identify and analyze LRCAT files.

I created a short-cut to the "PSE.exe" so I can launch the editor directly and skip the first window.

But, in LR, I import my photos and first do some keywording before doing any editing. I have a LR catalog of 90,000+ images that I can find on a moment's notice in several different approaches based on how I'm 'thinking' about the image. Don't give up on the Organizer without spending some time understanding what it can do for you.

For my PSE10 install, the short-cut points to: "C:\Program Files (x86)\Adobe\Elements 10 Organizer\Photoshop Elements 10.0.exe"

Update to your current version, if you find the short-cut idea useful.
