[Bug]: Token Network Filter - Network filter balance for Sepolia and Linea Sepolia is not correct

[seaona]

Describe the bug

Whenever I have Sepolia or Linea Sepolia selected, I see that if I click into the Network filter, the network balance is not correct and it's always set to 0.00001.
This happens both if I have Show conversion on test networks on or off, and Show native token as main balance.

Note: this issue happens behind the feature flag: FILTER_TOKENS_TOGGLE=1

Expected behavior

We should display the same native token balance as I have
