But since pushback works for everybody, it must be something in your configuration so, again, please indicate all the precise steps to reproduce it, including all the information I already asked:
- which airport you are using. if it's not default, please identify the scenery.
- which gate you are using.
- which airplane you are using.
If you are sure "it doesn't matter", then it must happen in a default airplane on a default airport so, please, indicate an example of a default airplane and a default airport in which this happens.
