Hey Csyyyyy0916,
I can understand you believe this to be the original account, but this EA account was not even created at the time you've mentioned last playing.
It could certainly be the same Steam account, however your progress is not stored on Steam, it is stored on the EA account level. If you link the same Steam account you've used in the past to a new EA account, your progress does not transfer - it will be lost. That's what happened here.
You'll instead see the content from progress made on this EA account, which is why you're still seeing a few items. If you're trying to access the old progress, you'll need to locate and re-link Steam to the old EA account.
