Hi, I’m sorry for disturbing you since this is an question asked about 4 years ago, maybe you won’t need this answer now, but I still want to post my answer here for those who have the same problem just like me.
Unreal does support Blueprint editable C++ enums, if you can’t edit you enum in blueprint anyway, check if ENUM(BlueprintType) presents and your enum is NOT A CONST variable/parameter when exposed to blueprint(this is what I ever did).
