First of all stop hijacking other forum posts with your question and do not keep posting multiple posts with the same question multiple times over just a few hours.
Keep doing that and you are likely to be blocked from this Corvid Forum.
As for your issue, it is not code related and therefore you should be going through Wix Support instead of spamming this Corvid Forum which is purely for code related issues only and not Wix Editor issues like yours.

If i understand correctly your looking for sub menu “databases” Believe they are testing new name “content manager” a simple look through menu options would have solved this issue,
