Sounds like there is some confusion here. If you swap the words Battle.net account for EA account, this is exactly how it works here as well.

Using your quote, "After the progress from a Console account has been connected to an EA account you may not switch the connected account and then receive the progress from the Console account."

This is the exact situation you've found yourself in. Your console account (Xbox) was already connected to one EA account. That EA account is where your progress is stored. 

So your progress from a console account (Xbox) has been connected to an EA account (the previous EA account). Because of that, you may not switch the connected account and receive the progress from the console account on another EA account. Your progress is still back on the original EA account.

If your recent Steam link was to this same EA account as well that would be why everything was level 1 - it was not linked to the EA account where that progress was stored.

In your situation, you'll need to unlink the Xbox account from this EA account and re-link it to the prior EA account instead. If you're wanting to access that content on PC, you'd just need to link your Steam profile to that EA account as well rather than this one.

If you need help getting that re-linked to the correct account, you can contact support directly so they can assist with that process.
