UST Files Acting Strange

[PieCrust]

Hello! I've been having problems with a UST file. Whenever I save it and open it again later, the file on Utau looks strange. It has all these bizarre lines.
At first, I thought it was a problem with the voicebank I was using (initially I was using Kohaku Merry's Tightrope V but when I switched to other VBs, they all saved like this. I can render the file just fine, but when I try to play it in the program, it renders and then doesn't play. I also can't edit notes easily. This hasn't happened to me before, and I've made and finished a few songs.
For extra context, I'm using Utau-Synth, and I'm using a UST from this site https://kerakerautau.wixsite.com/k3ra-entmt . Does anyone have any ideas as to what the problem is, and if there is any way to fix it?

I don't know where to change this in UTAU-Synth, but you need to change the "main" tempo from 50000 to 171:
