[Bug][Minor] Greater Glyph of Scaling Mana Regeneration

I was inspecting the Runes for Mana Regen when I noticed that the Calculation for the Glyph was incorrect.

What it says in client:

"+0.06 mana regen / 5 sec. per level (+1.2 at champion level 18)"

If I am to assume it's +0.06 per level then it should equate to +1.08 at level 18

I only noticed this because the Seal is +0.065 per level (+1.17 at level 18) which is a higher base value per level but a lower total value at level 18.
