Coupon code on membership plugin returning an error

OK so when I have the coupon code activated for membership signups, users are reporting an error when trying to use the coupon. When they use the coupon, the system accepts the discount and then they go to the page where they enter their cc info and when they click submit payment they are seeing 1 of two errors.
I have the coupon to only discount the "Finite" level which is the first month's payment of the membership.
You can see my membership levels here -->
The errors are:
-"Trial Occurrences must be less than total occurrences."
