Ioun Stones Effects

[Theocrat]

I am using an Ioun Stone - Cracked Dusty Rose. The validation report says that its not valid under current settings and effects are ignored. What setting do I need to set so that I can have the effects in place? I tried removing the PFS section but that didn't help and I can't really see what particular area I'd need to check or uncheck to make sure that those effects get shown and are in place.
In relation - with Ioun Stones and according to Seeker of Secrets - it is possible to implant an Ioun Stone. As PFS guide doesn't say that this is illegal, is there a way to mark that an ioun stone is implanted?
