PvZ GW2 (PC) Upgrades not unlocking

I'm following up on 2 week-after live chat session regarding with EAHelp about a bug I'm experiencing in Plants vs. Zombies: Garden Warfare 2 (PC).

I have two fully Mastered characters, those being Captain Deadbeard and Captain Squawk, and both of which are missing an upgrade, which should have been unlocked at Specialist rank. Despite both characters being fully Mastered, this upgrade still shows as a question mark for both of them, as if it was never awarded.

I have already tried the following with no success:

• Clearing the EA App cash
• Repairing/verifying game files
• Reinstalling the game
• Playing full matches with both affected characters
• Using Stars on the Fish in the backyard to give me exp

I would really appreciate it if this could be looked into and resolved. Please let me know if any further information is needed.

I *would've* given photo's of my problem, but apparently I can't give them on this post.
