Dynamic data linking database error?

Hi,

It looks like I am making a mystake somewhere but I cannot point out where. Basically, I have two tables: users and orders. One are created with a form, so by default Bubble integrates a “Creator” list. In my user I added all the unique ids of orders.
Yet, when on repeating group, I can only show the unique ID of the user.

To show you:

This returns the creator’s id, so that good.

This returns black. Bubble thinks it’s empty info, even if it is filed inside my database.

Would any one have an idea how to fix this? I check some videos, it looks like I’m doing that right -_-

After three hours, I find.
If someone has this issue, it was a table Privacy issue x)
