Before you create a coupon with the updated system, please carefully read the help information about the coupons.
The “Gift Coupon” is for a one time use. After it is used it will be removed/deleted from your coupon offerings. It will be gone after the first use by the first customer.
If you are creating a coupon to be used for a catalog then you will want to use “Permanent Coupon”.
To limit a Permanent Coupon to one use per shopper, check the “One time coupon” checkbox. Any number of customers can use the coupon then, but only once each.
