[Steam] Issue after purchasing Digital Deluxe upgrade.

So when the game initially launched I had purchased the Digital Deluxe edition. I don't regret my purchase there. However, with the start of season 2 I was browsing the store page and noticed a listing for a digital deluxe upgrade. I wrongly assumed this was a new dlc with the release of the new season. I purchased it not realizing it was the same content. I tried to request a refund on steam but due to the item being listed as DLC and including MTX it was denied. I explained that the duplicate content granted me no additional content or lux but it was still denied and was told to reach out to this support if anything else could be done. I'm happy to support Marathon I just was hoping to actually get something out of a purchase I made. At the very least have it so that steam recognizes as me already owning the content instead of there being a separate listing for the same content.
