I've recently resumed uploading to FT and have noticed a bug whereby the pricing isn't always correct.
It's correct for the first image (S=1 credit, M=2, L=3, XL=4, XXL=5, X=50), but then resets to S=1, M=2, L=2, XL=2, XXL=2, X=50 for the next one. Changing the answer for "Do you want to offer an Extended rf license with this image?" to "No" then back to "Yes" resets the prices to their correct values.
