Sound error with MuseBasic sounds

For some reason in MuseScore 4 a saw wave sample has been added to some instruments such as the glass harmonica. If you compare the sample of the glass harmonica in version 3 and 4 the difference is quite noticeable. You can still here the original sample but there is another sample playing at the same time. I also encountered this on some other instruments though I can't remember which at the moment.

Version 4.0 on Windows 11.
