EE + ER Rates are being combined for employees enrolled in lowest cost plan, why?

Here's a new one.

We have two plans. Plan A and Plan B. Plan A is our least expensive plan.

All reporting works correctly EXCEPT for Employees enrolled in Employee-Only coverage in our "ACA Affordable" plan. If an employee is enrolled, the 1095-C is showing the combined total of what the employee and what we, the employer, pays.

For example: Employees pay $80. We pay $800. The amount shown on Line 15 is $880.

For any other plan option (EE+FAM, EE+1) an employee is enrolled in, the correct $80 populates. If an employee is enrolled in and of the option in our more expensive Plan B the correct $80 populates.
