Master disapear (not shown in hideout)

I had only Tora in my hideout and do the dayly quest.
After that i add Haku to my hideout and do the quest.
(Tora stands at the left side, Haku on the right in my hideout)
I dismiss Tora and add Elron

--> only Elron was shown in the hideout (on the right side), haku was no more shown.
After doing Quest for Elron and going back, Haku was shown on the right side with the mark i should speak to him and Elron was not shown. I spoke with Haku but the sign to speak to him
don't disapear.

I have to login new to the game that both masters were shown in the hideout (only to go back to char selection doesn't work that both are shown in the hideout).
Aftre login new, haku stands on the left side, Elron on the right side.
