It's normal with confused new does. I usually make sure to plan for plenty of time to watch them so I can let them wear themselves out and calm down for the buck to get down to breeding before I have to go do something else. Every now and then I'll scruff one in the middle of the cage and let the buck mount her. Sometimes it's like a little lightbulb clicks on. "Oh! That's what we are doing. Ok, I can do that" and then they sit there mostly still for 2 more breedings. Sometimes they clamp down and just aren't ready.
I also just have a spaz who does those things for no good reason. A lot of my indoor cages had open fronts or tops because there was nowhere they could go and the sides were 28-40" up for laid back netherlands and a mini rex doe who won't hop over a 6" cage lip. Well that silly blue netherland doe I got a few months after starting this setup would get going so fast she would spin herself right out the cage. I had to finish all the doors and wire roof. She does the same if introduced to a buck. I have to make sure the cage is solidly closed and block off anything she can sit on (including feeders) because she will spin herself around and around until she starts running on the sides of the cage and ends up on top of things. The bucks just sit or hop in circles going "what the heck?" until she gets tired but if you don't block the bin feeders or hay silos she will stop on top of them when she gets tired. I have to pitch her off objects and wedge a box temporarily between feeders and the ceiling until I'm done breeding her.
