After working out how to create a second realm, I was able to load in the seed I wanted (2065486297). When the realm was first attempted, I tried inviting some friends. The realm did not load and the invites were spammed to all accounts invited. Second time creating the realm, I decided to load in solo and then invite from there. Currently there are no editable settings under the "Game" option. I can change the name, description, difficulty, and game mode. The normal Download World, Replace World, and Reset world options are available. (As well as the activate cheats, however I do not intend to use that feature.)

When loading in the world a second time, the spawn changes with the persisting bug of not being able to edit settings.  

Replacing world with first auto-generate backup restores me to the initial spawn location. 

Among the attached screenshots, I have included the realms that are currently active, with the realm titled "Progress" set to be cancelled upon the expiration of the current billing cycle.

The realm titled "iEndeavors" is the current realm I'm having issues with. 

At the time of Jira creation, there have been 8 backups auto-created.
