This binding issue would result in the engine 1 switch to not move at all. Which is why I asked in my first post to determine this was the issue, and OP already mentioned the bindings to the engine switches and it doesn’t seem to be coming from the toggle fuel valve problem.
Even if it is, it’s best to reset the profile you previously have with the current default profile (which already have them removed).
I’m doing a flight with the latest FBW A32NX development version, and there doesn’t seem to be any engine startup issue.
