Modify Maintained Spells Window

[scynx]

Ok, new topic, maybe more luck this time :P
I wanted to change the iconsize of the icons in the maintained spells window, so i opened up the maintained.xml and changed the size from 30,30 to 19,19 which worked without any problems.
The icons are smaller now, but there's a huge gap between them, just like if the icons would still have a size of 30,30. I looked around and figured, every buff-frame from 1-30 has a preset size which is defined by this piece of code:

<Page Name="Frame1" Size="250,32">

I thought it would be width*height and changed them to:

<Page Name="Frame1" Size="250,21">

to line up the icons without any gaps between them, just like it is under general buffs/debuffs. Sadly, it looks like i'm wrong because the gap still remains. Can anyone help me out here, i'm a bit lost now
