Error - Greater Glyph of Scaling Mana Regeneration

I'm currently looking over what new runes to decide to get, and came across an error in the text for the glyph stated in the title. The description claims: +0.06 mana regen /5 sec. per level (+1.2 at champion level 18) Did a quick calculation and the total it provides is actually 1.08 at lv18. At just a quick glance it appears to be better of the seal of the same type (claiming the correct value of 1.17 at champion lv18) and people may have purchased it thinking so. Please look over and fix the error. Thanks :)
