Please check the collections, is there any new collection that you have recently made, because it will be very difficult to determine in which collection images are.
I noticed the missing ratings in the last collection added. It was added 3 months ago. No collections added or deleted since then. The ratings dissappeared within the last 2 weeks.
May i know did you recently took a backup of the catalog that you are using.
We can open up a catalog from the backed up date when everything was up and running.
Im just going to reapply the ratings.
