taCenter does not work with edDataCheckbox

i made a small test program: One form, one TAdvColumnGrid. Then at one column i set
  Editor = edDataCheckBox
  Alignment = taCenter
But the checkbox remails left justified.

What can i do?

The problem does not occur when the checkbox is added with AddCheckbox.

Do you use the latest version of the component?
I just retested this here, new TAdvColumnGrid on the form, change for column 1  grid.Columns[1].Editor := edDataCheckbox and grid.Columns[1].Alignment = taCenter and this shows the checkbox centered.

indeed, i do not have the latest version. We will check it out.
