Is there a frame (vertical, horizontal or text) just before the bar where you want to change the duration?
2th question: which is the nominal duration (the current one) vs. actual (the one you want to change) ?
Curiously enough, there seems to be a particular “sensitivity” if Actual duration is changed to 3/8

For the record, the workaround is to first change the duration of the measure, then insert a frame to it.
