Hi,
Normally it works but when I want to show "special price" and select "FullPrice with TAX with discount" or "FullPrice without TAX with discount" it doesnt work.

Enable Debugging on plugin Configure page. And try to generate the feed file.
Send me the log file FoxNetSoft.Plugin.Feed.Manager_log.txt from App_Data folder.

I'll try to help you.
I can't reproduce your bug.
1. What NopCommerce version do you use?
2. What plugin version do you use?
