Breacher Assault Class - Extra Granade IS NOT ADDED (no matter what)

Know issues but want to clarify - Assault Class - Breacher Specialization - Extra Grenades . 

No matter what grenade I chose it's count is always 1 as shown on picture . OK maybe it's worded wrong and it relate only to "Launcher Grenades" of which is 2 , but when switched class to Frontliner everything stays exactly the same. 

It's a bug and should be looked into. 

Frontliner Specialization , everything exactly the same :
