[2020] Armor doesn't come back if you refund the next round.

The title is weird because its hard to explain quickly. Ex Round 3 I buy heavy armor and during round 3 I take damage and at start of round 4 I am now left at 39 armor. I buy heavy armor because I have money to buy, but realize my team wants to save, so I refund the armor I bought and then I am left at 0 armor, as opposed to my 39 I had. Is this intended?
