Bug when overwriting larger mixdown file

My version of cubase pro is 10.0.30 build 236.
I exported (mixdown) my project using mp3 format (but the problem may occur using other formats).
I then changed my mind and exported a smaller (shorter duration) mixdown, using the same name. A popup asked me if I wanted to overwrite. I said « Overwrite » and everything looked fine, except that the mixdown (mp3 file) had an extra piece of audio from my projet added to the end…
Has anybody seen this ? It took me a while to understand that I needed to manually delete the previous file for the process to work. In other words there seems to be a bug in the overwrite process.


This sounds familiar to me. I think I have experienced this in the past already.
