WoWInterface - kgPanels buttons are not hiding

A while ago humfras created this cool kgPanels script for my UI. I created some buttons in kgPanel and they only show up if you hoover them with your mouse. This buttons have text and a tooltip that explain what they do. I don't know it my problems are an error in kgPanels itself or with the script so:
Problem 1: The buttons are not hidden any more they are always shown I guess the onload self:SetAlpha(0) dosen't work?
Problem 2: The buttons are not transperent any more, I have set up the color in the AddOn to 50% but it shows up in 100%. I but this one is a problem with kgPanels.

The rest of this script works as it shoud I can still hide/show dominos bars with it text displays on mouseover etc.

Example:

DOMINOS BUTTON 5:
____________________
ON LOAD
____________________

Code:

self:Show()

self:SetAlpha(0)



self.frame = Dominos.Frame:Get(5)



self.defaultFadeAlpha = Dominos.db.profile.frames[5].fadeAlpha

self.defaultAlpha = Dominos.db.profile.frames[5].alpha or 1



self.oldExpAlpha = Dominos.Frame.GetExpectedAlpha

self.newExpAlpha = function(frame) return self.defaultAlpha end



if self.frame.sets.leilanofade then

local f = self.frame

f.GetExpectedAlpha = self.newExpAlpha

f:UpdateAlpha()

end



if GetLocale() == "deDE" then self.tooltip = [[

|cff00bfffLinks-Klick:|r

1. Verstecke Aktionsleiste 5

2. Leiste 5 bei Mouseover



|cff00bfffRechts-Klick:|r

1. Zeige Aktionsleiste 5

2. Leiste 5 bei Mouseover

]]

else self.tooltip = [[

|cff00bfffLeft-Click:|r

1. Hide Action Bar 5

2. Bar 5 on Mouseover



|cff00bfffRight-Click:|r

1. Show Action Bar 5

2. Bar 5 on Mouseover

]]

end

else

  f.GetExpectedAlpha = self.oldExpAlpha

  f:UpdateAlpha()
