Hi there, @alasadi.m1738… I’m guessing the issue is related to there being data in the development database for the related data type, but there is no data in the live version for that data type.
The development and live versions of the database are separate, so you will have to copy the data from development to live in order for the data to show up in the live app. To copy data, go to the Data >> App data tab, and use the red Copy and restore database link. It probably goes without saying, but be super careful when copying data from development to live because you are overwriting the live database with whatever is in development.
Hope this helps.
