I'm not sure if this is by design, but when a DataGrid is added and removed, the Events remain present.
This page has only one Form and one DataGrid
But all of the orphaned Events from previously added and deleted DataGrids still remain.
It might be intentional so I'll just remember to delete all of the events after a DataGrid is removed.
On a side note, I need to test to verify, but it seems to take the settings from the DataGrid with the lowest value, highest in order. I was trying to add a $Filter to Invoke #7 but I think it wasn't getting picked up because it was not in Invoke #2.
