Hi,
My apps are suddenly acting weird. Previously, when I selected an item from the gallery, it navigated or moved to the form screen that contained the data that needed to be edited. However, all of a sudden, it stops working. When I click an item, it does move to the form screen but shows an empty value. I've done research on a similar issue and found a lot of posts similar to mine, but all the suggested fixes did not solve my problem.
This is my gallery. The "Update Item" is the button.

This is my form. When I click Update Item, it should display all the value of these cards but it stop doing that.

Thank you in advance.
