Can't key my frame. Harmony 10.3

I’m working on a new rig and for some reason the program wont let me place any keys on the frames involving the head. The rest of the body will key, but for some reason, the head refuses. Also other options on the timeline toolbar menu is greyed out. I’ve done a lot of work so far and I want to find out what I did to prevent this from happening in more crucial stages later on.

Have you somehow disabled animation on drawing layers?
