I have a form with a dropdown (SharePoint list Choice column) that works perfectly fine:
Items = Choices([@'LAR Approval'].LSA)

I needed to add another dropdown to the same form, as well a Choice column, with two options
Items = Choices([@'LAR Approval'].ChargingBasis)
Result: the dropdown shows Items 1 to 15 instead of the available choices in that column.

I created a new screen and a new form, but now all dropdowns in this new form show items 1 to 15, not just the dropdowns bu as well the people picker dropdowns, and even the LSA dropdown which works fine on the original form:


I checked all the properties, they are the same. I refreshed the data source, no change. I tested the SharePoint list, choices and people pickers work as expected. Where do these Item 1 to Item 15 come from? Why doesn't it load the choices?
