Drumline Audio Upload Problem

I have the newest musescore version and I have the Drumline extension downloaded. I recently write two pieces and they sounded fine. But when I uploaded them I had no sound. A day later, which is today, I opened it on the musescore app instead and now the parts are played back like Latin or World percussion (conga, whistle, wonky sounds, etc.) I’m not sure if there was an upload problem or what but I’d appreciate all the help I can get! :)
