Coupons Disappearing and not Updating Daily

I have a coupon press theme and my coupons are disappearing everyday. I will start off with 350 coupons that I import and within the next day I will only have 112 the next day. Everyday I have to go to the admin panel and import coupons, but they don’t stay for any length of time. The people at icodes said it must be something with the script I bought and that I should contact the owner of the script. Any solutions .
