TL-50 Reduced Spread Attachment does nothing.

Product: Star Wars Battlefront II
Platform:PC
What is your issue related to? General
Summarize your bug The TL-50 reduced spread attachment does nothing to make the spread less scattered. The attachment seemingly has no effect and thus seems useless to equip right now.
What is your gamertag/PSN ID/EA Account name? StubbornTrooper
How often does the bug occur? Every time (100%)
Can you tell us the date (MM/DD/YYYY) that you saw the bug? 3/20/2018
What time did you see the bug? (HH:MM AM/PM) 7:20 AM
In what game mode did the bug occur? Arcade Mode
What is your time zone? PST - GMT - 8:00
Steps: How can we find the bug ourselves? Equip the TL-50 heavy repeating blaster rifle. Unlock the reduced spread attachment with the improved cooling attachment already equipped. Fire the TL-50 with and without the reduced spread attachment equipped and notice the mod has no effect. Arcade and all trooper-related Multiplayer modes seem to have the same result.
What happens when the bug occurs? The TL-50 reduced spread mod's bolt spread is the same as without the reduced spread attachment equipped.
What do you expect to see? A somewhat more accurate bolt spread that does not shoot wildly to the sides when you equip the reduced spread mod. Otherwise you can only hope the spread is near the target when you're firing the TL-50.
