While using a Switch node on a custom enum I defined in blueprint the values displayed reset after I haven’t look at it a while (I presume a restart of UE) They all reset to “New Enumerator 0”, 1,2,3 etc. I have to recreate the nodes to get back the proper display values.
Its a known bug.
Right click on your switch node and choose the “refresh nodes” option or something like that.
Hope that helps.
