Transfer for CC payment wants a category

I just made my first credit card payment. I used the "record payment" button and told it which account the money came from. But now it wants a category. That doesn't make sense to me. Every other transfer doesn't ask for a category. I thought the whole point was to categorize things on the credit card as they happen.

Here's what I'm seeing without the amount:

Any help is appreciated! Thanks.
