Batch SET Variables Not Clearing

Okay, so I'm trying to make a batch game with a lot of choices in it. The code for the main action menu section can be found below. All the variables except %c% are set above. Anyways, whenever I get to this section in the batch, I will type in my selection, and it will just reload the menu. Then, the next time I type in my selection, no matter what I put, it will go to the selection that I had typed previously. I have no idea why it does this, because I have the line that says "Set "c=" which should clear it, right? And why does the menu only reload the first time I type in a response?

Any help would be appreciated. If you need more explanation, I'd be happy to give some.
