Campaign Milestones Stuck after Server-side Reset

Since EA has disabled its customer support email (and since that hasn't been very useful in the past anyway), I thought I would try bringing up an issue here. Any thoughts at all on what I could do would be appreciated. 

The problem:

Two campaign "Scavenger" milestones (find every hidden item in a mission) are stuck as incomplete in the Career > Campaign screen, even though the corresponding Select Mission screens show those hidden items as already found:
- Under Covered Skies: Scavenger: Career shows 3/4, but the mission's collectibles display as unlocked/found
- Until Ashes: Scavenger: Career shows 1/2, but the mission's collectibles display as unlocked/found

Root cause:

Some time ago, an EA server-side event reset milestone progress on my account (and others; this was widely reported at the time): any milestone not already completed was zeroed out. Critically, that reset zeroed the milestone counters but did NOT clear the per-mission "item found" flags. This left my account in a contradictory state across two of EA's data fields.

Why I cannot fix this through gameplay:

Because the items still register as found in the mission, the game will not let me re-collect them, and the milestone counter only increments on a fresh collection. On console, this would be fixable by deleting local save data to force a campaign reset, but the PC/EA App version stores this progression server-side with no player-facing way to reset it. I've tried uninstalling and reinstalling, and playing offline, but neither of these methods worked.


Is there any way to get EA to do one of the following (any of these options would resolve the issue):

1. Manually credit the two affected milestones to complete (Under Covered Skies: Scavenger 4/4 and Until Ashes: Scavenger 2/2), or
2. Perform a reset of my campaign progression for these two levels so I can replay and re-collect every item cleanly, which will re-feed the milestone counters correctly, or 
3. Perform a full reset of my campaign progression so I can replay and re-collect every item cleanly, which willre-feed the milestone counters correctly.(I'm fine with losing campaign progress, as long as online progression, unlocks, credits, and other earned milestones are preserved.)

Alternatively, is there anything else I can do on my end? Thank you to anyone who can offer comments or guidance.
