Missing Thompson M1928 mastery assignment after reached 10 lv of weapon

after reaching weapons level 10, i dont recieve any mastery assignments since the last update. so far i got 3 weapons to level 10. for first two, support granted me mastery assignments manualy but for commando carbine, they dont have a solution. apparently, they dont have this weapon in their scripts and so, they cant add it manualy. but however, this are just temporarily solutions. we need a longterm one. playing on PC. please help. @EA_Atic
