Tough to work with

I dont know why, but this app just doesnt want to work with me when I use my iPad mini. I record one layer and place it on a track, and it always cuts off a small part of the end when I listen to it again. Also, it sometimes doesnt sync all the layers correctly. It would be working fine with all the layers on beat, but the next time I press play, it tends to have a track thats either playing too early, too late, or doesnt even play at all! When I tried to export a song and email one of my recordings, some of my tracks stopped playing in the background, and it didnt come back on. What is the problem? Does this happen to anyone else? Can I fix it somehow or avoid it? Plz do fix this app!
