I can't stop the slow attack from stacking

[Silvermane]

How do i prevent frost attack from stacking? and is there anyway to set the speed reduction?

It is a frost tower on a wintermaul wars map and my frost tower is stacking the frost attack and it will pretty much stun. Well not stun just pretty much stop the units sent, they move but barely. The tower also has splash vs air and ground and i would like to keep it that way (just incase someone sugested some single freeze thing)

-Thanks

No matter what i do! it still stacks! I even chose all the (non-stacking) things ive tried for the past 6 hours! And now i thought i almost got it. It doesnt stack when i hit single units but when i hit a single unit and it splashes to another then it stacks! and i dont know why. For some reason i have ice (non-stacking) at the moment and the splash effect to other units is a poison effect (the look) but shows as ice which its suposed too >_< Any sugestions?
