Selection of lists and tracks go wrong

If a selection in Export/Multitrack Playlist was made and the selection changes the list always stays at the “old” selection.

Example: 4 Lists.
I select list 1 and 2: the export confirmation aks about 63 files

I deselect 2,3 and select another one (list 3 with 2 songs) and try to export – the same 63 songs will be asked for comfirmation.

The whole programm seems to be buggy. Playing with selections and pathes can bring a lot of pain. I using uTool in a quite heavy way and change often the tracks and playlists (I do it for 9 singers/bands) with more than 100 playlists and more than 1000 songs.

I wrote a lot of software in the last 25 years. I know about the mistakes in programming. But I too know that this kinds of issues only will happen when the software is grown up by try and error.

Some further issues I noticed:
Default location path (in settings) changed – dont know why. It happens 2 times. I have not found a way to reproduce it.
Sometimes MIDI-file was not exported. Happens sometimes (only when midi-file exists on disk)
Pre/post-button in player has no function.
Monitor mix/Direct Out not visible in player.
