Off FX not working correctly!

Hi Guys
lets say i have 11 Robe 600E Spot in my show.
I do select all of them (see that in programmer), open the effects engine, go to the tilt table and set it to off.
I do save this as effect palette.

1.after creating the palette it's still greyed out in the effects directory.
Why that?

2. when i do open+effect (that off effect i just created) i see the selection of the fixtures, but fixture 9 is missing.
I repeated this several times. But still the same.
Is this a bug or feature? :)
I cannot save an off fx preset GLOBAL right? (tried that but still see the selection)

Please give reply on that.
Thanks
Jay
