Finger poser top joints not responding

Hi everyone. My GMod’s finger poser stopped working yesterday; I can adjust everything except for the top joints, which as you can imagine is quite annoying. There’s no way to pull a trigger properly.

I have two installs, one on my rig and one on my laptop. I’m having the problem with both, and I have tried reinstalling to no avail. Does anyone else have this issue, or an idea of how to fix it?

Thanks in advance.
