Stuck in ground while using elytra

I was gliding with the elytra from a high place (450 blocks high) and what should have happened was I'd land and my player would be able to walk around normally. Instead when I reached the ground it acted like I was still gliding but stuck in the ground. Oddly I could jump, sprint and sort of move but the player model was still stuck in the position of gliding and when I looked somewhere I'd move in that direction, just like gliding

Not quite sure how to do this, but
1.Wear the elytra
2. TP up [I did this command: /tp [Player] 0 450 1
3. Glide to the ground and it should occur
