Audio streams in multipart films problem

I have some films which have 2 parts and 2 audio streams in both parts.
I can choose audio stream only for a whole film. It should be ok but it’s not. Audio stream for a 1st part is equal to selected but for a 2nd part it is always 1st stream (default?) in file. When I try to change stream during playing 2nd part I get an error message with no stream change.

Sooo, any confirmations? Is that only by my side? Any suggestions what to do? That’s the real problem for me :frowning:
