MuseScore 2

When I choose rise (arsis) before the beginning bar and I come to end of the score, I don’t know how to delete the rest, so when playing it, it goes wrong (say 2/4 too long).
Can you help?

Ciao, I didn't understand anything...
Wait for a better answer but in the meantime add some information and, if you want, the score.

Edit: maybe Edit/Measure->Split or Join?

And please don't attache a doc(x) if all you write within can be written directly.
