Kingdom of Amalur: Reckoning no DLC playable

I also published this question in the German EA Forum, but since I expect the audience here to be larger, I am also posting my problem here.

After many years I reinstalled KoA:R from my EA account including both DLCs as the following screenshot from the EA App (PC, Windows 11 64-bit) shows:

I know that THQ later acquired the rights to the game but, the installation worked, and I can play the main game even though it won't connect to the EA servers.

Unfortunately neither DLC is playable/startable so I was wondering if anyone knows a way to start them since, for example, there is no Commordire Garrick in the Seaform Tavern.

I appreciate any help and thank the helpers in advance.
