Laser Designated Vehicle Damage Mission Not Advancing

I dealt multiple hits to enemy vehicles marked by a squadmate using the Laser Designator, with both the MBT-LAW and SLM-93A. The mission progress remains stuck at 0/1000.
The targets were properly designated by a squad member, full lock-on was achieved before firing, and hit markers appeared. However, no mission progress was recorded.
Restarting the game and reconnecting didn’t fix the issue.
