Had the same issue when I got my '22 Lariat. I ended up buying a mongoose and FDRS and did it myself. You can get details on how its done here:

I added them to mine after I spoke with my dealer. They indicated that it wouldn't cause any delays. However I don't have a production date yet. I saw on one of the FB groups that someone ordered a platinum with them and it was built awaiting shipment.
I ordered mine on 7/19 at the discount price of $885. Got an email that said 7/25 - 7/28. After reading your post I went to check on mine and when I look up the order it says order not found.
I thought it was an error as well. I wanted the SR Lariat with both packages but it wouldn't allow but if I choose the ER Lariat it comes with both packages. Looks like you can get both on the ER XLT as well.
