Requesting help updating mod (MW5Mercs)

Hello everyone,

I need some help. I have several mods in EGS for MW5Mercs, and one of them had become stuck last Auhust.

It says " Mod Approved Congratulations! Your Mod has been reviewed and approved. If you have any questions, contact support."

Since then, I can’t upload new mod files, can’t change descriptions, can’t recall it. Completely locked.

When I try anything, I get “There was a problem saving your progress. Please try again”

Who do I ask to fix this? The publisher of MW5Mercs, PGI has already contacted Epic about it and nothing happened.
The mod in question:
https://store.epicgames.com/en-US/mods/mechwarrior-5--da37677c575b4c599449662b731808a7

Whoever knows the secret to solve this, please help me. You are my only hope.
