[Bug]: Confirmations - Stuck transaction as Speed up/Cancel doesn't let me edit gas (stays in Advanced)

**Describe the bug**

If I Send a transaction with Advanced custom gas, whenever I try to Cancel or Speed up that transaction, I am not able to edit the gas and I see Advanced as gas set.
If the gas was originally low, that transaction is then stuck.

**Steps to reproduce**

1. Start a Send
2. Edit Advanced gas and set very low values
3. Confirm
4. Click Speed up/Canel
5. See you cannot edit gas
6. Confirm
7. See the tx is stuck
(I'm using a custom RPC, not Infura, unsure if this has something to do)
