[SOLVED] PayPal Shipping

After sending a live order through HikaShop Starter, I received the following Admin email:
____

Paypal payment notification refused:invalid amount

Hello,
A Paypal notification was refused because the amount received (24.94USD) is different from the order amount (19.99USD)
____

The price difference is the $4.95 shipping configured via PayPal, and no shipping charges are added via HikaShop.

Additionally, after a transaction is completed, and PayPal accepted the full $24.94, in the backend of HikaShop it shows that the Sale is only for the product amount, $19.99.

I haven't removed the shipping configuration from PayPal yet, because that PayPal account also accepts orders from other sources than just this website, so I can't just assign shipping via HikaShop. Are there any additional settings or code tweaks that could improve this communication between HikaShop and PayPal, or will I need to assign shipping in HikaShop and connect it to a different PayPal account without shipping configurations?

Thank you in advance for your time.

HikaShop 1.4.4

Thank you. I had a hunch that would be the simplest solution.

So far this has been a very nice component, and I appreciate your time & energy on developing it.

oops, nevermind!
