Am able to reproduce the issue with STX on and off.

1. I see a call to get the next nonce when the confirmation screen become visible.
2. I see that the value that would be returned for the next nonce is correct.
3. However, I see the previous, now incorrect, nonce value being shown in the confirmation of the second send transaction despite the call for the next nonce being the correct/expected nonce value.
4. When I click reject, I see the custom nonce value input field get updated from the previous incorrect nonce to the correct next nonce value right as the confirmation window is closed.

I think this is a component state/hook issue due to points #2 and #4

The enablement of smart transactions should be fixed by https://github.com/MetaMask/metamask-extension/pull/26433/commits/2a487f23ec8290f3a939a5c850cac85299056be2.

Looking at nonce stuff in https://github.com/MetaMask/metamask-extension/issues/26979
