Can't delete clef and key signature after adding less stretch
I wanted to bring the measures 3 + 4 into the the same line and did that by selecting both and choosing "Add less stretch", which pretty much worked well. However, the clef and key signature of 4 (which was the only maesure on its line before) did not disappear, and I don't seem to be able to delete them. Any idea what I'm doing wrong? Musescore file attached...
Thanks in advance,
