Support gem Uhtred's Augury not working properly

The tooltip clearly says you have to use exactly 2 other support gems to grant the +3 bonus.
With patch 0.3 it was working properly but since 0.4 it fails to work.

Having Cast on Crit slotted with a skill gem, Uhtred's Augury and 2 other support gems and it only gives the bonus if I use only 1 other support gem.
