Multiple winning bid emails: Congratulations! You have won an auction

Hi, I’m testing your auction plugin and in general it look promising.
There is one serious problem than prevents us to use this.

When auction is won, plugin send multiple auction won notification messages to winner. It’s like one message per minute and they won’t stop… they just keep coming.

Title of this message is “Congratulations! You have won an auction” and it has details about auction.

I needed to deactivate whole plugin to get those messages to stop.

Any solution to this problem? If this get solved, we probably purchase paid pro version.

Waiting for your soonest reply. Thank you.
