Semi auto then full auto on full auto

Having a weird selector issue with a G&P Zombie Killer CQB-R here:

Safe and semi auto function fine. When the gun has been fired in semi auto, then the selector moved to full auto, the gun will fire one round (like semi auto). Releasing the trigger and pulling again, we get full auto. From there, pulling the trigger continues to give normal full auto.

When full auto is working and the selector is moved back to semi, then back to full auto, the gun continues to fire in full auto.

It seems to consistently fire a single semi auto shot before firing in full auto only after the gun has been cycled at least once in semi auto.

Any ideas? The selector switch and plate seem fine, but I can't think of what could be going on inside to produce this problem with such repeatable consistency (literally every time).
