What version of Grid2 are you using?

r936  

Issue:
Only show dispellable debuff, can you add this as an option like in retail or is it not possible in Classic?

The dispelablel debuff code was not removed from classic version, if this part does not work is because blizzard does not provide that information in classic. You can use debuff types, for example if you can dispell "Magic" types, track the the "Magic debufftype" status.

Yeah, i am doing that at the moment, but this way i have to make multiple profiles because the dispels depend on which healer i play. 
When the "dispellable only" (instead of selecting magic, poision etc.) option was there, i was able to just work with 1 healing profile, which is nice.

I know there are other frames which shall be unnamed, that has this option in Classic, so figured i'd ask...since Grid2 are my fav frames :)

Download r937-beta-classic, report back if this version works (i could not test the new code for all classes)

Am testing it now, can not find the new option, there are no "dispellable debuff" option or anything like that.

There is no new option, changes are internal, it's the same than in retail, you have to create a buffs(plural) status, and check the dispellable debuffs filter option. 

Ah okay, i see it now! 
Don't remember doing this in retail, will test this out though, sweet.

I don't understand  how you could report a non working option that you never used. So  i tested the old code and It is working fine in classic (at least for a mage), i spent an hour fixing something that apparently was not broken :(
