Negative items in Vault overflow

Bungie Account Name - Moira#4231
Platform - Steam
Description of Issue - After exfiltrating from a Dire Marsh run as Rook, my Vault was overflowing. After making enough space and preparing to spam transfer everything that was in the overflow list, I was abruptly stopped by these two stacks of Heavy Rounds. One was a max stack of x 60 and the other a stack of x 21, but hovering over either of them changed their stack value to x -2,139,074,560, and they were "Invalid" to move to my Backpack or my Vault. Hitting the "Sell All" key successfully sold them with no unusual effect on my Wallet.
