Most commands on the switch don't work, or come up with a sentence of feedback that does not make sense.

When I try to use the "/give @p barrier" command, no matter how I write it, something is always wrong. When I thought I had finally gotten it with "/give barrier", it then said "Syntax error: Unexpected "": at "ve barrier>><<". I'm not sure if it's something I'm doing, or if it's a bug, but I figured I would report it nonetheless.
