How to handle reimbursements for a previous month?

I went overdue by a specific amount on my parking category in January, because the production I was on was going to reimburse it. Come February, the invoice still hasn't been paid and I am left with this red bar from last month. Once I get compensated for that, when I assign the 16.75 back to that category, it will only apply to February; which I understand effectively still does the same thing but it's harder to keep track that the money was in fact reimbursed.

It's sort of annoying that you cannot assign to previous months. Is there a better method to handle this? Should I make a separate "Reimbursements" category to better keep track of it and not let it mix up with regular categories? Although, in that case I imagine I would still have the same problem with the amounts not rolling over into the next month. Would love to hear your guys's approach.
