What version of Grid2  are you using (Version is displayed in General/About Tab) ?

 v2.2.9

What game client version, classic or retail, windows or mac and language are you using ?

Retail, windows, english.

What steps will reproduce the problem?

 I use the same profile for all my classes/specs. When I'm playing resto druid the frames act normally, as soon as I switch to boomkin spec the frames grey out as if someone is out of range or in a different phase, even when right next to me - in raids, dungeons etc. Spells still go through but visually it's wrong. I also tested guardian and feral, they work fine too. Not sure what is causing the boomkin grid2 to be weird when it's exactly the same profile. 

Did you try having Grid2 as the only enabled addon and everything else disabled?

 Yes

Was it working in a previous version? If yes, which was the last good one?

 Seems to be an issue since the last update.

Please provide any additional information below.

I've attached two pictures so you can see the resto/boomie state of the frames.

Goto the range status configuration and check the range setting (statuses/targeting&distances/range), which range option is selected ?

maybe a spell that is not available for boomkin spec is selected.

Probably you did not pick the Rejuvenation talent in boomkin spec (this is the spell used to check the range if heal range is selected in range configuration).

Goto the range configuration and select 38 yards, another posibility is to select "spell range" and set "Regrowth" as range friendly spell.

If i remember correctly "Regrowth" spell is always available for all specs.

Another option is to update to version 2.2.12 in this version Regrowth is used (instead of rejuvenation) when "heal range" is selected.
