Animation Motion Help

i try to follow this tutorial “UE4 Blueprint Tutorial 17 - Mage Spell Caster (1/3) - YouTube

my leg in skell animation is in air in such time…

what wrong with this?

i dont want root motion cause this skelatal mesh doesnt have root node

it could be an issue with the character capsule component being too low below the character or not adjusting with the animation. that’s just my guess though as i don’t work with the animations in unreal that often.
