[Please don't ignore lol] Idle animations stop playing upon switching weapons. (?)

I'll get straight to the point. I was working on Server-Sided animations for my fps, and noticed that when I switch weapons, everything works fine until I switch back to my primary after switching to my secondary. The animation for the primary weapon, which I had then switched to from my secondary weapon, did not play and so the character was stuck with the idle animation of the secondary weapon but had the primary equipted. I'm not good at explaining things, so if you have questions, (which I'm sure you will,) I'll be answering them.
