Localization "KEY" Keep Changing When Restart Editor


I’ve been dealing with this bug for weeks but couldn’t find any fix yet.

Some of my Localization Keys and Package ID’s keep changing everytime i restart editor. As in the SS below :

  • I have 8570 text at dashboard but this bug only occurs at 110 of them.
  • When I Gather text in Localization Dashboard, I get these BPs with a completely different KEY Like :

  • Most of them has same Master BP with same struct, But there are a lot of BP that uses the same master BP and does not cause any problems
  • This bug appears at 4.18 then i upgrade project to 4.19 and its still occurs
  • I tried to assign new KEYs to this Blueprints, but still getting the same result
  • I tried to change folders, rename the struct but nothing works so far.

Any help would be great
Thanks a lot

EDIT: Migrating project to clean one doest fix that either

What kind of assets are those? Does the issue persist if you save them?
