Multiclass Proficiencies on level up
I believe there is an issues with automated application of proficiencies on multiclass characters for example a Fighter/Thief 6/6 is only showing 4 weapon and 4 non-weapon proficiencies. Assuming I'm understanding the progression for multiclass out of the PHB revised it should gain 1/1 proficiency in warrior every 3 levels giving at least 2 more proficiencies in both weapon and non-weapon at 6/6. Any help would be greatly appreciated, there's a good chance I'm just not understanding the rules here.
