After changing the database, this item in the gallery is not displayed

I tried cloning the app by replacing only the database, but it's not working.
Specifically, the contents of "this item" in the gallery aren't showing up.
Strangely, it's visible in edit mode but not when published.
Of course, this problem wasn't occurring in the original app.
The gallery is a nested collection that stores reference data, and the items causing the problem are records within this collection.
This is the first time I've encountered a situation like this, and I'm very confused.
This problem is keeping me up at night and worrying me.

    • What is the Items Property of the Gallery ?
    • Is your collection or datasource is being set on the screen visible or some where else.
    • Are you using the gallery control or some other control to display the data?

    Gallery items are collections


    This collection is displayed on the screen in the gallery.
     
    After much trial and error, I found that
    when creating a nested collection with Clearcollect,
    I add the lookup values ​​using addcolumns.
    When I reference those lookup values ​​with thisitem, they're all blank.
    Strangely, except for the ID...
    Am I dreaming?
