Special Characters suddenly occur in MS 3.2
I my recent score I have observed an odd effect. Suddenly some special characters (see attatched file, I have marked them yellow) occured and strangely they seem to bee undeleteble. I may have accidentally typed a shortcut, I don't know. Undo does not delete them.
As an additional effect the special character prevents me to add a slur beween two notes that are separated with this character.
Does anybody know how to get rid of them and what I could have done wrong?
