Keyboard Issues

I noticed that minecraft offers keyboard support on the xb1 now... so I went and bought a wireless Logitech MK530 keyboard and mouse combo. Issues I have run into...

After hitting "enter" or "t" and typing message you cant hit "enter" or "t" to send message. I have to first hit "B" on my xbox controller to minimize the xbox chat dashboard on screen before I can send the message. Sometimes the xbox keyboard does not appear and the chat feature works within minecraft itself.

I also am having issues with sticky keys due to shift being used often to not fall to death. I do not see an option to turn on a toggle setting for shift as well.

Randon issues with my character randomly being stuck walking forward "w" or stuck walking left "a"

Lastly the game will freeze when playing in a server "mineplex" if I begin typing a messafe to fast. Nornally freezes on sky block survival teams mode.
