Buggy scores on Ipad MuseScore app

I use the MuseScore app on my Ipad. Recently a lot of scores started to format weirdly. The distance between the treble and bass clefs is way too big so that only 1-2 rows shows. It sometimes crashes when I exit the score. I can't even view some scores. A few days ago it was fine. On the website is fine, but I preferred using the app. Does anyone know how if there a way to fix this?
