Hello,
Tagging and rating are only contained in our database for free users. For paid users, you can write the tags and ratings to the file itself or to a sidecar file. You can see more details on how we handle metadata here: http://www.fstopapp.com/metadata/
What software are you using to tag your photos? Can you send us an example photo? The best way to do this is through our support email: support@fstopapp.com
