Spawn Ai With ID's/Tags At Runtime

I have a unit Character Blueprint with a widget component that accesses the state of the unit’s health , the problem here is, it works fine if its one mob. With more than one instance of that character blueprint, the widget accesses the health of all the current mobs and when killed and i’ll get pending to kill errors. There is a way to display the health by doing it with other components but thats a last resort.

The fix here I’m assuming is with ids or tags stored in an array at runtime. I don’t know how to set it up properly for it to make sense to me since data managing is something new to me. any help is GREATELY appreciated since its a complex topic for me.
