Wheel of Tree containing Steelwood Stance Only benefits Warstaves

I noticed when I equipped a regular staff with these passives I lost all attack block benefit. (i think it added it to my spell block instead) But if I equipped a warstaff the benefit returned to attack block.

Ignoring the Heist bases:
Regular staves can come with an implicit for spell block or global crit.
Warstaves come with an implicit for attack block.

Depending on what warstaff you're comparing with, you're changing your attack block by 20-25%. And wheel you're referring to adds up to 20% attack block.

When I equip a regular staff the bonus from those points changes from "Attack Block" to "Spell Block". Since that is not what is stated on the passive points it looks like a bug to me.
