Flying In Survival

For some reason I am able to fly while in survival, I cannot access the creative menu where I can take any block and I do not have operator on this world, I can also still die to mobs, players, etc. Everytime I fly though, I almost instantly die as it says I suffocated in a wall. My friend does not see me fly but more of bounce rapidly up and down super fast. I am not too sure which versions this bug is on but it has only happened to me on 1.17.2, im not too sure if its the hotfix or beta. I fixed it when I re-logged but it is still a bug.
