AdvStringGrid. AutoSizeCells and RowHeight with Checkboxes

I'm trying to get roughly the same rowheigh in a db grid

I do this by

DBGridDaten.AutoSizeCells(True, 4, 4);

Result without boolean:

Result with Boolean Checkboxes:

How can I minimize the difference? Is the difference a bug or a feature?

I understand this relates to the height of the row?
What Delphi version is this and is there high DPI involved? Is this also the latest version of TMS VCL UI Pack?
