Single-Port Brake on M2010 ESR keeps re-equipping itself.

I always take off the single-port Brake from the M2010 ESR factory sniper rifle (i equip the empty slot) but after a few matches or when i start BF6 again the single-port Break is back by itself on that sniper rifle.

I want to equip the empty slot that costs zero points and does not affect the stats of the gun , but the game insists on re-equipping the single-port brake.

Please fix this bug.
