Elytra not working after teleporting with command

Elytra works fine until I teleport to a destination with commands.
It stops working after I teleport, but It works again if I relog to my singleplayer world.

What I expected to happen was:
A normally working elytra.

What actually happened was:
Elytra just didn't want to open/work properly.
