Some actor visibility in world outliner is off everytime i restart UE

Hello, i’ve got some mesh where visibility is turned “off” everytime i restart UE. Happening in world outliner

Those mesh has been in the past merged into ISM with merge actor, they are the original mesh. I already see all the option :

  • Visibility
  • Is Actor Editor only

And everything is fine on this side, any clue ?
