Instantiated NPC will not change from order taken state to movement state, when original NPC will.

Iv been struggling with this for a while and tried so many different solutions. Im creating a bar management game and iv got an enum state machine which works perfectly for my original NPC. but when the create npc function executes it creates the npc, it is in the idle state and when i click it the state changes to order taken, works great until i set order complete to true using the same way as my original npc through my serve mat, but it just wont change to the movement state which it should.
what am i doing wrong?
