Folders show 0 photos after having been restored, but all photos show in the "all photos" category.

My computer failed recently, so I restored it from backup, including Windows OS Lightroom Classic and its catalog. Actually, I installed a fresh Windows and fresh installs of the Creative Cloud products, then restored a backup of the most recently backed up catalog. I have about 100,000+ images in the catalog, stored on a NAS which also crashed at the same time. It was backed up as well and has been restored. The image files that were on the NAS are now on a different drive letter on DAS. The catalog shows all =~100k+ photos under "all photos" but all of the counts in nearly all the individual folders show "0" photos. Interestingly, I've found I can re-import that folder, uncheck the box to skip duplicates, and the photos come back, along with all my edits and selections. How can I straighten this out? So parts of the catalog are intact--just not all of it.

Thanks,
