[Imbuing] problems with imbuing mana leech

[Eyes of Origin]

I've searched all the threads and cant find any info regarding this...
Twice now I've tried to imbue mana leech onto weapons and it says theres room for the max of 40%, but when I actually go to imbue it onto the weps, it wont allow me to go higher than 34% or 37%.. any clue as to why?
One time it was a war fork and this time its a comp bow.. and there is plenty of room to add these mods at 40%.

mana leech is determined by a formula That is determined by SSi ! so this may be your problem !

Basically, as SSI increases, leeches have to decrease - or visa versa if you put SSI on a weapon first.
