No- I do not know why the universal settings for commissions are not applying. that should not be happening.
Just to double-check.. you set the commission rate here?
wp admin > woocommerce > wc vendors > commission (tab)?
This should apply for all vendors unless the commission is overridden on the vendor level by you setting a special rate in the vendor’s user settings.
I’ll see if I can combine the accounts..
