In MacOS Sonoma 14.6 when deleting measures in the beginning and later redo it some instruments play back as if the measures were still deleted

In MacOS Sonoma 14.6
In a score with orchestra where the strings start and the solo-instruments jump in later.
When deleting measures in the beginning with only the strings and later redo it (putting them back),
(only) the staffs of the solo instruments plays back as if the measures were still deleted ,meaning the solo instruments start the amount of (previously) deleted measures sooner then written on the score....
So the score is ok, but the playback starts sooner of only the solo instruments (in my case the flutes)
I have to close the score(saving is possible) and when I reopen the score everything is fine again.....
