Cannot delete defunct trustlines with 0 balances from xrp wallet. Blocks account delete.

[jrbruce]

I'm running into the same issue with two wallets (cannot remove defunct trustlines w/ 0 balances):

Problem trustlines

Issuer Name | Justcoin
Address | rJHygWcTLVpSXkowott6kzgZU6viQSVYM1
Currency | BTC

r3YPg3GMt5NhvHduzbwQNJ4EBt2wTgMjyE

Issuer Name | rEcVacFXML9JrVZNqB4c3NCtMochx8RF9V
Address | rEcVacFXML9JrVZNqB4c3NCtMochx8RF9V
Currency | XIB

Limit and balance are both 0. They are still showing as a trustlines in gatehub, xumm and XRPL. Unsure why these trustlines cannot be removed from my wallets.
