SIMS PACKS NOT BEING RECOGNISED

I have had the sims 4 and many of the expansions packs for years without issue, I also had the sims 3 and and city skylines on my origin account. I t redeemed a product code for the Sims 4 for Rent today which worked successfully and was added to my account. 

There was also a sims 4 update for the base game to download - as this started all of the content from my EA account has disappeared - all the games and everything. This is hundreds of pounds worth of Games just gone and I can't see how to get them back.

When I log into origin the app is trying by itself to re-download them without being prompted but each time is failing. 

Could I please be advised how this can be fixed? 

Thanks
