Master Level Spell Activation Problem

I've created two new spellcaster units and gave them "new" Master level spells. I've checked everything in the spell editor a dozen times but for some reason the spell doesn't recognize that the caster is Master level and won't "activate". I've fooled around with the spell level integer, created new spells to see if they work and i've made no progress. Every spell that I designate as required a 2nd level of research won't activate despite researching to the max. Any ideas what's wrong?

Thats a WE problem, so you'll have to do it via triggers or wait for Blizzard to solve the problem.

Thanks for the reply. I can't really do it with triggers so i guess I'll wait for a new patch, whenever that comes.
