Can't see anything in Blueprint Event Graphs?

As the title says, When I open up ANY blueprint doesn’t matter which one and click on the Event Graph, there is nothing in them to see, they are empty. I can see the functions listed on the left, but cannot observe their contents either. How do I fix this?

Only a small bit of the coding for ark is done with blueprints. There are however a few things that have graph work done in them. Allo, Moschops, the nocturnal one & Titanosaur for example.

So if I wanted to copy a mechanic from one dino and give it to another, where would I find it and where would I put it?
