5 MW Green Laser on DRS-IAR doesn't work

When playing (both multiplayer and training grounds) after the California Resistance Update, if i use 5 MW Green Laser on DRS-IAR it doesn't register as an active attachment (unlike 5 MW RED and 50 MW Green which both works correctly). It's only not working on DRS-IAR of any package, other weapons are not affected, but i did't check all.  Playing of PC, Steam
