Levitation kick BUG

/execute @a ~ ~ ~ detect ~1 ~ ~ stone 0 /effect @a minecraft:levitation 1 255 true

This command works but if I use this at a greater height from the ground(like 4+ block high) and than after I fall on ground in /gamemode 2/0 it kicks me off several blocks high(30+ block).
This is for mapmakers like me game break bug/glich.

Thanks
