I've noticed that everytime I make a purchase on GOG, my saved Paypal choice of payment *always* defaults to my bank account as the prefered source of income, despite of me already having configured my Paypal account to choose my own Paypal salary as the prefered one.

I've tried to remove Paypal account and add it on another purchase, to no avail. Looks like I'm now forced to manually check Paypal salary everytime I make a purchase, otherwise it auto charges it on my bank account.

Why is this happening? Is there anyway to solve this issue?
