Contacted support again today via text. talked with Mariel and just asked for a refund of the overcharge instead of trying to get her to fix the root issue. She said it was approved and I should see it in 7 days. Also asked for a refund for the previous invoice in the calendar year. She said it was approved and I should see it in 14 days. She also said that the states would be automatically removed now that I've asked for a refund of the overcharge.
I'll check in with you next month to say whether or not I actually got the refunds and the states removed from my multi-state list.
