Madsen MG Mastery VI missing after restart – gold parts locked

Hello. I have an issue with the weapon mastery progression for the Madsen MG in Battlefield V (Support class). I completed Mastery I–V, and I have already unlocked the Gold Receiver and Gold Stock. However, the remaining gold parts (Gold Muzzle, Gold Barrel and Gold Magazine) are still locked.

Earlier, the Madsen MG Mastery VI assignment appeared for me. I activated it and started progressing it. After restarting the game, the Mastery VI assignment completely disappeared. It is not in my active Assignments, it does not appear under Special Assignments, and only the Proficiency assignment for the Madsen MG is available.

I have already tried removing all active Assignments, changing servers and regions, playing with another Support weapon (KE7) and completing its Mastery tasks, returning to the Madsen, making kills and finishing full rounds, restarting the game and the EA App. Nothing worked. Mastery VI never appears again.

This means the mastery progression for the Madsen MG is stuck in a broken state on my account.

Could you please help by either resetting the Mastery progression for the Madsen MG, so that Mastery VI becomes available again, or manually granting the missing gold parts (Gold Muzzle, Gold Barrel and Gold Magazine).

Thank you.
