What were you doing when the issue occurred? E.g. respawning a squad mate at a beacon, using an ability, a squad mate left the game. Switch firemode of R301 or Flatline (same behaviour)
Did your squad mates also experience the issue? I don't know but I think yes.
How many matches had you played in a row before the issue occurred? Occurred in caustic takeover
When did this happen? (dd.mm.yy hh:mm) 12.03.21

What happens when the bug occurs?

When I change the firemode of a R301/Flatline, the icon of the firemode (see HUD of the weapon) does not get updated. The actual fire selection works. Only the icon is not updated.
What should be happening instead? When I change the firemode # to single fire, the icon in the HUD of the weapon should show the single bullet icon (instead I get the infinity icon)
Steps: How can we find the bug ourselves? Equip weapon (R301/Flatline) and select fire mode.

Update:

• I tried all weapons with a select fire mode. I found out, that there is same behaviour on Hemlock and Prowler.
• Also I found a UI bug for Prowler. the Text for select fire: auto/burst does not appear
• I can also reproduce the choke symbol bug https://answers.ea.com/t5/Bug-Reports/UI-Bug/m-p/10152356#M53035 (firing mode icon is also carrying over when you pick up a new weapon)
