To turn WordPress's automatic paragraph formatting back on for coupon terms, uncheck the Auto P Filter option under Coupons > Options > Display.
By default Coupon Creator removes the wpautop filter from the coupon terms field, which is why the Auto P Filter checkbox is checked out of the box. That default gives you tighter control over spacing so line breaks in your terms are not turned into extra paragraph gaps.
If you would rather have WordPress add paragraph and line-break formatting automatically, go to Coupons > Options > Display, uncheck Auto P Filter, and save. Your coupon terms will then be run through wpautop like normal post content.
Switch it back at any time by re-checking the box.
