TF2 Ragdoll Fingerposing Error?

Back in the day, Before the Gmod Update, I had multiple problems with fingerposing the TF2 Ragdolls, Some of the models (Mostly Scout and Engineer) would be unresponsive on the two joints above the finger. When I bent them, they did absolutely nothing, and just sat there. I tried many methods to try and fix it, but I ultimately resulted to re-installing Gmod. But to no avail, the problem still arose. This is becoming a nuisance and I cant find a single working solution anywhere.

So please, if you guys have a way to fix this, let me know.

Just in case you dont know what the fuck im talking about, heres a screenshot
