Some Items in Launcher Vault not showing as owned on Fab

Summary

I have found at least one asset that I owned in my Launcher Vault (ByteBox Inventory) that when viewed on Fab is not in my library and only offers purchase options.

I have too many items in my Vault to check them all. Are issues like this expected to be resolved, or do we have to find and report them individually?
