How to stop Church Bell echos?

Hello! I'm not very knowledgeable on Musescore, so please forgive me if this is a silly question.

So, I'm attempting to rearrange a piece with some instruments in Musescore. I included some Church Bells in the music for dramatic effect, but the bells echo pass their notes and onto rests and even play a few other notes that I didn't even place there. The ogg file I've attached should show what I'm talking about. I've tried messing with all the sliders in the Mixer, but it hasn't really done anything.

I appreciate any and all help!
