Partial Refund Shows Pack as Not Purchased

A few days ago, my boyfriend built me a new PC. I did not have this issue on my previous computer - all of my purchased content was recognized by the app and loaded correctly in the game. (For years, mind you.) However, since installing the EA App and The Sims 4 on my new computer, the app is failing to recognize 3 packs. The packs are Dine Out, Backyard Stuff, and Spa Day. All three were purchased at the same time in 2016 according to my order history. I received a partial refund for these packs on the same day I purchased them. If my memory is correct, I was charged full price during a sale / promotion, hence the refund.

There is only one support case in my records, and while I assume it's related to the refund, I can't verify this. It says it was updated in 2017, but clicking on the case does not show any information. Not sure if that's normal, or if maybe EA auto-deletes support messages? 

These are the steps I've taken to troubleshoot on my own:

1. Removed mods & cc
2. Deleted "The Sims 4" folder and loaded the game to regenerate a fresh folder
3. Repaired the game through the EA App (multiple times)
4. Uninstalled the game and the app using Revo Uninstaller
5. Reinstalled the app and the game
6. Reviewed the advice in this thread. 

I have attached screenshots of my order history showing the initial purchase and the refund. Additionally, I have attached screenshots showing that the packs are recognized as owned in the game's "PACKS" tab, despite the content not being usable.
