Hi @Vic1491,
Could you please tell me why you inset two controls within a single data card?
Actually, one control in one data card represents one field value from a record. Further, a control within the data card inherits the field value corresponding to the data card.
Each control within the card should reference Parent.Default to get at the field's value. This strategy provides a level of encapsulation for the card so that the card's Default property can change without changing the internal formulas of the card.
So, if you want to keep the AQE # box value, I am afraid there is no way to achieve this in Power Apps unless that you only want to make it in a new form where you could input whatever you want, however I don't think this is your issue.
Just remember that each control within the data card could only inherit a field value from a record if you want to reference to Parent.Default. I think the Update property is combined to the answer from the drop down box, that's why the issue you described occurs. Once you reference to Parent.Default, AQE # box will always display the answer from the drop down box.
