I have one form with is a list of records. Click on row opens the edit form with data ready for edit. But, I added an aggregate column to show count of child records. After adding that one column, the edit form does not seem to work as expected. The list still shows the records as before and the count column is also correct, but click on the row opens a 'New record' form instead of edit; completely blank and it behaves like that too, enter field values and save creates a new record that can also not be edited.
I am sure I am doing something wrong but do not see anything obvious to add to the form/field properties.
PS. version is 3.8.3
