after upgrading M2E Pro module to version 6.4.14 (former svn revision 11425, new revision 12591), we face wrong calculations and display of price, totals, tax in order detail view.
I can see, that in some cases tax is calculated twice, but I also have an order for which non of the numbers is correct:
Tax-settings for products and delivery are 19%
Display of ordered product is totally ok.
Subtotal is correct also.
But after that, everything is broken.
This affects orders from ebay, amazon and shop itself.
Maybe you could reproduce this issue and give me some hints how to fix this.
