i created a Grid, the data gets grouped by Tournumbers.
When i change the Tournumber of a position to push it onto a other Tournumber, sometimes it creates a duplicate Group with the already existing Tournumber.
Example:
[Group 1016]
(A 1)
(A 2)
[Group 1032]
(B 1)
(B 2) [Moved to 1016 by changing the Tournumber in the Tour column]
[2. Group 1016]
(B 2) [Moved from 1032]
So the position moves not into the already existing Tournumber. This doesnt happends for all Position just certain ones.
Does the component some sort of sorting or matching Values when grouping?

The position with the green border was moved from 4006 to 1240, here you can see it creates its own group.
The property GroupDataSorted is set to false. - Didnt fix my problem.
I dont have any other sorting/filtering enabled.
Maybe someone can help me or does have a idea.
Thank you!
