ROBLOX Default Animations Interupts My Animation?

I set the AnimationTrack priority to action, but the ROBLOX animation still over rides it. (only works for the client, not for other players)

Filtering Enabled is on.

local Animation = script:WaitForChild('Animation')
local AnimationTrack = nil 
local ActiveTracks = nil 

local State = nil 

function AF_LOADANIM(name, id, speed, state)
	Animation.AnimationId = id
	State = state
	
	if AnimationTrack then 
		AnimationTrack = nil 
	end
	
	--SET TRACK--
	AnimationTrack = Humanoid:LoadAnimation(Animation)
	
	AnimationTrack.Name = name
	AnimationTrack.Priority = Enum.AnimationPriority.Action
	print(AnimationTrack.Priority)
	
	--PLAY--
	AnimationTrack:Play()
	
	--ADJUST SPEED--
	AnimationTrack:AdjustSpeed(speed)
end

set priority
