Notes in range in transposing instruments colored red in ARM

Hi, I have recently installed a MuseScore nightly version in Arch Linux in an ARM tablet.

In a new staff with newly added transposing instruments (like Tenor Sax) all input notes are red colored although they are not out of range (see attachment). The clef is correct. When using Concert pitch in the same transposing instruments, the key is changed, but the notes should be changed as well and that doesn't happen. When unchecking the Concert pitch, the key should have been brought back to it's original shape, but that doesn't happen - a different than original key is displayed. The notes remain the same.

This doesn't happen in Windows version of MuseScore, here the transposing instruments work fine.

Thank you
