When editing the Game Settings from the Manage Realms UI, I'm often unable to exit the settings menu and return to the main Realms page. 

It doesn't seem to matter if I'm adding or removing resource packs, changing game settings, or downloading a backup. 

After I've made changes to the settings and attempted to leave via the Edit"World_Name" button, the UI changes to the "Inititialzing Upload" message, then changes to the "All Done" message with the "Let's Go" button. Upon clicking the "Let's Go" button, I'm returned not to the Edit World UI, but to the Game Settings UI.

This can continue in an endless loop, with no way to exit this UI, save closing the game.

Occasionally, it will exit to the "Applying Packs" message. If this happens, then I'm returned to the Edit World UI as expected. 

Steps to reproduce: (See Attached Video)

1. Enter the Realms "Edit World" UI via the Pencil icon next to the Realm name.
2. Highlight/Click the desired world, to bring up the "Edit World" button
3. Click "Edit World"
4. It is not necessary to change settings, however, this can be done if desired.
5. Exit the Game Settings UI via the "<Edit: World_Name" button.
