4% transaction fee on product on e-commerce plus plan?

Hi all,

I just signed up my client with the e-commerce plus plan - where there should be a 0% transaction fee on products.
I added a test product but somehow lost 4% on it when I purchased it. The tax rate is included in the product price, as the Japan automatic tax included is not available for Japan (only US, Canada, and Australia I believe).

Would anyone know what’s going on? My client saw this from when he was collapsing on content, and I’m a bit stumped on how to fix this - as I don’t want my client losing 4% on purchases for no reason.

Can anybody point me in the right direction?
