[Other] Advice with buying BF1 and BF4

Although I don't own BF4 & 1 I have acquired all of their DLCs and premium passes when EA was still doing giveaways. In Origin it shows that I own BF4 premium and its DLCs but not for BF1. If anyone was in the same situation before, will buying BF1 activate the extra content? If not, they do show up in my Order History so I can contact support about it. Getting BF4 & 1 at $2.99 a piece is just to good of a deal to pass up.
