Invisible buttons on the UI?

I'm really new to Unity (just started messing around with it a couple days ago), and for the most part I've been good with online tutorials and such, but yesterday I came across a problem that I just can't figure out. I'm trying to script some animations, but the UI -- specifically for the parameters -- isn't appearing. The weird thing is, it's still there, just not visible. I can click on the buttons and bring up menus, but I have no way of knowing where they are without clicking randomly.
This happens regardless of what parameter type I use, whether or not they have scripts attached, and whether or not any animations are currently using them. I've tried messing with the UI settings, restarting the program, attaching/reattaching scripts, and restarting my computer, but nothing seems to help. It's really hard to edit something when you're feeling around in the dark.
I can provide a video on request if it would help solve this issue.
Any help would be appreciated!
