I already did that. They told me:

I was able to reached out to our back end team and was advice that for employees who has different location from their resident, there will be multi state charge.

This response makes no sense. I only have 1 work location in 1 state, and therefore should not have to pay a multistate charge.

It appears this functionality is based on the whether the employee has a different state in their personal address when it should be based on their work location. How can I correct this and not be incorrectly charged?
