Green battle stones not working?

[Simmias]

So I'm in the process of stoning my pets so I can increase my score on the site, it's srs bizz
But atm I can only use green battle stones on Critter pets and nothing else. Anyone else had this problem? I can use the flawless blue stones but green ones just don't register
