Resource pack menu in realm settings gone

What I did
I tried to change the texture pack for my realm, but I can no longer find the menu for it.
When I look to edit a local world, the resource menu is there, but not on realms.

What I expected
To find a menu to edit the resource pack.

What happened
The place where I expected the menu to be, was blank. (See Screenshots to compare local world vs. realm world setting screen.
