WTF? Changing the amount of magic a mana potion recovers?

Okay, I'll just get to the point. In this map I'm making, I want there to be a variety of different mana potions, each which recover greater amounts of magic, but here's my problem. In the ability editor, I try to edit both "Item Mana Regain (Lesser)" and "Item Mana Regain (Greater)", but neither of them seem to have a field for editing magic. Why is this, and can I change that?

If all else fails, I suppose I could do it through triggers and dummy potions, but I don't wanna jump to that unless I'm absolutely sure I can't do anything else.

It should be there under "Data - Mana Points Gained"

If you do use copy-and-paste to drag the mana potion, the field will gone disappeared (a kind of bug)

You can use restoration potion instead (it works)

There are a lot of abilities having this bug too(e.g. healing salve, clarity, generic rejuvenation I-VI, etc)

You could just edit a scroll of mana.

It keeps the mana points gained feild there
Set its AoE (area of effect) to like 1
Change icon
Change animation art
Change Sound

There you go, your new potion of mana

Yes but a scroll of mana will still work even when you have full mana points, a potion won't... unless of course you want to make an extra trigger :-)

well if your that stupid to use a mana potion when your full then you deserve to lose it

I'd have to agree with that... the scroll way is the simplest to do anyways.
