This forum is answered by the community, not the staff.
Regarding your question, it's best to try contacting the staff directly. From what you've described, it seems to be a bug, but it's the first time I've heard of it. I'm more inclined to think it's a misconfiguration.
Itch allows two ways to get paid. One is where Itch is the seller. In this case, it doesn't matter how people pay; all the money goes to Itch, and you then have to withdraw it from Itch.
The other way, and from what you've said, I think this is the one you have, is where you collect payments directly from customers. In this mode, Itch doesn't receive the money; instead, you receive it based on your settings.
I've never used "direct to you," so I wouldn't know the options, but if my hunch is correct, you might have a PayPal account set up and you've forgotten about it. It's best to try checking the payment settings of your accounts.
