Text Curser Position in v21

Hello Bricscad Community.

I recently changed to Version 21 and encounter an inconsistent Text Cursor.
When I for example want to enter a radius for a arc and it has more than one digit the curser stays in front of the first digit so when i want to enter 120 i end up with 201 or insted of -90 i end up with 90-. Is this just a Bug or a new setting that i miss? This Problem is not constent and doesnt seem to reappear for some time or with speed of entry.
Best regards Mario
