[Finale] Cautionary time signature

[Pierre Bailleul]

Hi all,   I'm working on a single instrument part with a lot of time signature changings. At the end of a staff, the last measure show a cautionary time signature. That is wrong : I don't understand why the staff lines of this measure ended against the page margin and the cautionary time signature is out ? When I reajust the system margin to the left, It's worse... Thanks for your help.   Pierre.
