Order Detail page after checkout shows wrong amount applied

Thanks for this great free plugin! We hope to buy the pro versions as our business grows.

THere was an error on the Order Details page after checkout.
Our gift certificate is for $25.
We made a test sale for $14.00

It sucessfully brought the total down to “0”.
However, the resulting Order Details page showed
Gift Card Payment $-1.00

It might be a little confusing to the customer.

Thanks!
Pam
