Having trouble making NPC move with blueprints (get AIController)

So I’m very new to unreal engine and have been going through tutorials and what not to get more acquainted with the interface. Ive been through a few and seem to keep running into a problem when trying to make an NPC move at all. Im not sure if the tutorials are just old or if theres something im not aware of.
I’ve attached a photo showing on the left my blueprint and tot he right is a Youtube video. As you can see I have a BLUE Get AIController, While the tutorial shows a green one with less options. Whats going on here? I dont know how to get the other version and everything seems to just not work because of it.
Hope someone can point me in the right direction. Thanks!
