DataViewGrid Input with EditOnKeystrokeOrF2

Hello,

since a few weeks I have a problem with DataGridView Input using EditOnKeystrokeOrF2.

When I go to a specific cell and press for example ‘1″:

if  the cell already has an value, the old value is overwritten an the cell gets ‘1’ and the cursor is at the end of text, if i press then ‘2’ the solution is ’12’

That is Ok

But if the cell is previously empty, the cell gets ‘1’ (this ok) but the cursor goes to the beginning of the text, and if i next press ‘2’ the solution is ’21’

that is wrong

Can you please tell me why or how can i avoid this.
