We have created a feature for our clients where they can create their own Column groups.
We are facing problems when we add a column to a group and then have the same column in the grid as an individual column.
For example Group Column A has children Child A, Child B, Child C. Also, we have a normal column Child B in the grid.

I think the issue is that both columns have the same field property.
So far we have found issues with grid summaries and grid selectedCells where we get data for only the leftmost column. But there also might be other issues that we haven't found yet.
Is there a way to keep both columns with the same field?
