Key Attributes on Pro Clubs not giving correct discount

I have noticed that for two archetypes (Target and Engine), the key attributes of strength for Target, and Interceptions for Engine do not actually provide a discount on AP cost. The cost is the same as it would be for builds where the stat is not a key attribute. Can this get fixed please as it puts these two builds at a disadvantage, as other builds with key attributes that work as intended essentially get more AP points available for use compared to Engine and Target.
