There's one website that from where I purchased a product with my paypal cash card but to my surprise, the amount I spent is taken from my main paypal account, not from my paypal cash card. It has never happened before. And this happens only with this one site. How's this possible? I shop online all the time with my paypal cash card (including from GOG) but this never happened to me before. Any idea?

I use Paypal,but from my main account.This paypal cash card is something I've never seen before,but in all honesty didn't notice or look for.I would be asking Paypal what the problem is.
