Pictures not showing up

This is kinda odd, but I'm missing 31 of 36 photos in a folder. The bottom-left shows "5 of 36" photos and when I open the folder for that date all 36 RAW CR3 files are in the folder but the preview pane only shows 5 of the 36 photos. Not sure if I accidently hid them or what? I tried reseting the preview folder by removing the "previews.lrdata" folder, and that did nothing. So not sure where to go from here...
