[Bug]: Send - Transaction amount is changed for a queued transaction, when changed on another transaction

**Describe the bug**

Whenever I have a pending transaction from a dapp, if I start another transaction from the wallet, and set the max amount, I can see how then the initial dapp transaction has changed its value to the max value of the second transaction

**Expected behavior**

Transaction values should be preserved, when I change another tx value
