Trying to use the structure block.  I am able to get it using the /give command.  Other commands such as /fill, /clone, /clear, etc., work just fine.  However, when I place the structure block, I cannot access the GUI to access the features of the structure block.  Also, when placed, the block appears to have a "-" (minus) sign in the center of the block. 

I obviously have the mode set to creation mode, since the other commands work.  However, I am not sure how to check or set the permissions.  

I am not sure what version I am using since it is on my xbox one.  I assume it is the latest released version since my system is setup for automatic updates.  Are structure blocks not supported on the Xbox version?  Any idea when or if they will be supported?
