Why do my coupons keep disappearing?

I have entered several coupons over the last couple of days. And each day, when I come back, all my coupons but one have disappeared. I am a little short on time as the my order form goes online today.

Any help would be appreciated.

Looks like you chose a coupon limit based on "By number of uses" , but it seems the number cannot be seen

So, we need to escalate this so they can fix the view of this section.

Meanwhile,  I would suggest you to chose "None" in order to quick the problem somehow.
