The free promotional items aren't included in DAO:UE, and have always had to be installed separately.
I know Origin downloads and installs them (and I believe the GOG version of the game does as well), but I'm not familiar with Steam's offering... though a quick glance at the product page for the game does not seem to mention the promotional DLCs being included.
So, first, I'd recommend confirming whether or not the promo item DLCs are installed > Click on 'Downloadable content' on the menu load screen:
That will open a list of all installed DAzip content (both Bioware and any community created mods). If the promo DLCs are installed, they'll be in that list:
If they aren't in the list, then the next step is to determine whether that is an issue with Steam, or not. And if Steam does not include the free promo items in their DAO:UE package, they can be downloaded and installed manually from Bioware's CDN, via the Dragon Age Wiki > Downloadable content (Origins)
The Download links is not working anymore and when ive moved to the new link provided https://help.ea.com/en-us/help/faq/dlc-for-classic-games it only shows the DLCs that i have already installed in the Ultimate Edition i bought in Steam. Ive even tried the https://dragonagekeep.com and redeemed it but its still now showing in my Downloaded Content
As someone who wanted to get the promo items on my steam account without having to buy it again on Origin and the game not recognizing it from Steam to origin it's easier to use this link:
http://dragonage-dlc.narod.ru/DLC_manua.htm
and download the dlc individually and then use the DAupdater to upload them into your game. Please be advised that some content may require you to use a CD Key but for the promo items that don't well there you go.
