The Display value could be incorrect for your table.

1. Go to your Groups table

2. Right-click on any of the columns

3. Select Configure -> Dictionary

4. In the filter add, Display = true

Ideally, you should not be getting any records or there should be a single record which is for the Name field.

In case you get something else, ensure only the Name field has Display checkbox set to true, and other fields have Display = false
