I haven't tested all, but it appears the spell IDs might have changed since RBS was popular?

I tested with a warrior that had Battle Shout and RBS was not reporting buff status on group for it.

Yes, the IDs changes, even the Buff on some class, It'll be updated when I'll be able to fix the error you reported me earlier #5

<3 Thank you for your hard work.
