Playback adds unwritten Sonds in Score for Violas (section)

I stumbled upon an issue, where the playback adds a g♭’/f♯’, even though only a♭’/g♯’ is written down. I was able recreate the issue in the score down below (Demo.mscz).
– It occurs only when the note note directly before or after the a♭’/g♯’ is an e♭’/d♯’.
–> It does NOT occur in any other octave or transposition I tried out.
–> It does NOT occur when one of the notes is any other note I tried out.
–> It does NOT occur when a rest separates the notes.
– It occurs in any rhythm.
– It occurs across bars.
– It occurs only when the selected instrument is “Violas (section)”
–> It does NOT occur with any other instrument I tried out.
– I occurs with different dynamics, however in f and in mf it is the most audible.

I am using MuseScore Studio Version 4.4.2 and Muse Strings on Windows 10.
