Field spec active abilities not working

After scoring enough points to unlock the extra active ability, the icon goes green, and a 6 keybind is shown over but you aren't able to use the ability like in beta. Sometimes the keybind 6 will disappear from above the ability, sometime it will go gray and not activate. 

I think this is under reported due to the increase in points needed to be able to use the ability, vs in beta when you would typically get it by around the halfway point in a match. 

Have not spoken to anyone on PC that has been able to activate the abilities.
