Coupons not appearing

Hi guys, i have membership installed here:

I am having two issues with coupons.
1. When i add a coupon it does not appear in the list of coupons. The coupon can still be used on checkout but cannot be edited.

2. If i create a 100% off coupon (I want to use this for some beta testers) it still brings me to paypal to complete the transaction and paypal will not allow payments for $0.
