Title/Description

Token balance not correctly updated after sending out all tokens

Environment

• Browser: Firefox
• Safe: https://rinkeby.gnosis-safe.io/app/#/safes/0x9D2407C6b6c1C307AB54Adb01627Ba0845e3Cddf/balances
• Wallet: Metamask
• App Version: 2.12.1
• Environment:
  • production (Rinkeby)

Steps to reproduce

1. Select a Safe with an ERC20 token which has a USD balance. I used this Safe and this token.
2. Token balance looks fine:

3. Send out ALL tokens to somewhere else (I sent them to another Safe)

Expected result

• Token balance and USD value goes to 0

Obtained result

• USD value goes to 0 but token balances does not.

Misc

The tx service has the correct data as far as I see it: https://safe-transaction.rinkeby.gnosis.io/api/v1/safes/0x9D2407C6b6c1C307AB54Adb01627Ba0845e3Cddf/balances/usd/

The issue seems to be when you transfer all the tokens you have, getting your balance to 0. If the balance doesn't reach 0 then they get updated just fine
This doesn't happen with ETH, that one works fine and updates to 0 just fine.

This snapshot was taken 1h after transferring all tokens from the safe to other accounts, and they still show funds.
