Elytra

i found a Glitch while i was flying around with the Elytra. i only had the enchant Mending on it. i landen on my feet but it didnt change back to Walk mode. it was Stuck in Flying mode. i have a few screenshots. im gona try to put it in the Attachment. while i was walking while flying mode was activated i could jump higher and it going to where i was looking if i was moving or jumping. then i switched to Creative mode and when i tried to Fly the wings wouldnt go back to Flying Mode. i was stuck in Walk mode while trying to fly.
The elytra wasnt Broke or anything. it had 243 durability left.
