Any idea why my enum stop working?

So I am trying to get my player into sprint state. Here is my declaration:

And to debug, I print out the value of my current movement state in tick function:

So I am thinking, if everything checks out, my current movement state should equal to 0, but here is the value when I click play :

This suddenly happened and I can’t get into my sprint animation anymore. Any idea why?

So I tried different ways to debug. It seems like the value of this enum can’t be updated even if I hardcoded it.

But my another enum works perfectly and can be updated as the game continues.

It feels like I lost connect with that enum only. Any idea why?

Is that the only place where it is modified?
