When publishing a form it warns me, "Warning: Data in these controls will not be saved to a field." And "Control 'CPIStatus' is connected to field 'CPI Status' on layouts:
- Desktop"
On testing, it indeed does not save. CPI Status is a Choice control and it is connected to matching column. If I delete the control and recreate it by dragging it from the List Columns bar the result is the same. We are on SP 2013 and Forms 2.11.5.20
