Values from Interface function are not set

In order to pass information from a custom Anim Notify State C++ class to my Anim BP and Character C++ class, I am attempting to use an interface. The purpose is to pass several different values (an Anim Montage and a couple bool values) from the Anim Notify State to the other classes that call the respective interface function, and use those values from the interface to set values within those classes. The issue I am running into is that the values from the interface are never set. When I apply a print string function to the interface event, nothing appears. I receive NO compile errors and my editor DOES NOT crash, so I believe I am on the right track, but I’m missing something.

Anim Notify State - C++ File - For Anim Blueprint
