Unable to teleport to back to world spawn point in Creative Mode for Windows. (MCPE)
I began and finished all my builds at the world starting point, coordinates 1424 63 10.

Steps to Reproduce:
open up Primary save file "phenoms world"
notice you are next to a mountain with falling water
type "T" for the chat - type in "/tp @s 1424 63 10 - hit ENTER"

Observed Results:
game will teleport you back inside the ground just under the foot of the mountain
(which is in another region of the world I got super lost in).

Expected Results:
To drink an ice cold beer after returning home.
