Discount vanishing at checkout

I'm using redshop, and when I apply the coupon code I created in the Cart section, it works ... till I get to checkout. Then the coupon just vanishes as if it wasn't applied.

Any input would be appreciated, thanks!

Hello,

What versions of AwoCoupon and Redshop are you using?

Redshop seems to be 1.1.11 and AWO is 1.01

Ok, I have tested it with those versions and not getting the problem. Is there anything specific you are doing that may cause it? In setup or flow? Have you tried to switch your template to the default one to check if it happens there?
