[Plugin: Amazon Payment Advanced WooThemes] Display Issue

Dear Community,

i have some trouble with the plugin of WooThemes called “Amazon Payment Advanced”. After hours of investigation i think i have identified the issue but i have no idea to resolve it.

Once Buyer logged clicked on “Pay with Amazon” and logged in the checkout will be modified to hide the WooCommerce Address Form. Instead of the WooCommerce Form the Address and Pay Method Widgets from Amazon will be displayed.

A style command “style=display: none;” is added to a wrong <div>-division, because this container including all forms (Amazon AND WooCommerce Address) – so both are not visible…

Cld someone give me a hint where i need to search and how i can change the “style=display: none;” to a different container in the theme/plugin ?

Thanks for your support!
