V5.4.3 Interfaces losing implementation after reloading project

Running into this issue in 5.5.4 using P4V. Project is upgrade from using 5.4 where the player already had the interface implemented. All other previous implementations work great and I can edit them without losing data. The new getter event was added after upgrading to 5.5 where no matter what I do (adding a random print string node, dragging in random nodes and not hooking them up, connecting the actor component node into the output) It always defaults to as if I never touched it on restarting editor.

I hook up the node. Save, restart editor, and it’s gone. I’m not submitting or anything, it just disappears like I was never there.
