win58 on "[Plugin: WooCommerce - excelling eCommerce] Cart % Discount Coupon not working"

Has anyone had or seen this issue with wc 2.02?
A coupon using a set amount of currency will work, only the cart amount give error.
When entered ie: 10% and hit Publish, the error is "please enter a number" and if just enter a number, it accepts it but coupon won't work. Thanks
