Hi,
your trigger enter will catch ANY triggers, so what you likely want is a more constraining trigger rule, using TriggerEvent Action and you filter by tag "player" so that only the player will trigger ennemy
Also, to debug your fsm as is and check what indeed triggerd the ennemy, simply use the action getTriggerInfo on the state coming from the trigger enter event and check which object it triggered, then you will get a better understanding of what's happening.
Bye,
Jean
