Editor forgets ENUM for Bitmask in Blueprints

Hello,

if i create a ENUM for a Bitmask and use this with a integer-var in a BluePrint all work fine.
But if i reload the Project the Editor forgets the Correct ENUM for the Integer Variable…

I think this is a Bug.

In 4.18.1 is still remains a bug. Once you reload the mask enumerator falls back to the Flag 1, Flag 2 etc list which is silly.

Still bugged in 4.21.2

The same thing in 4.26. Is there really no solution?
