E-Mail "Your Order Confirmation" // codes are not replaced

Hi folks,

i'm using WP 3.3.1 and Marketpress 2.7.

Still none of the codes in the E-Mail "Your Order Confirmation" are replaced (CUSTOMERNAME, ORDERID, etc...). Strange thing: codes in the Subject-Line of that E-Mails ARE replaced.
Also the codes are perfectly replaced in the "New Order Notification"-Mail.

I Re-Installed the Plugin Marketpress 2.7 via FTP - didn't remove any DB-Entries for that Plugin before.
Still same behavior... What can I do?

Thanks in advance,
