That's strange... it should work fine if you bought it DLC from same region store as the main game regardless of account...
Sounds to me like the issue is the DLC being account-locked for that particular game... The Crew, Steep and some other games do this, meaning only the account that purchases the DLC gets it... but those games are always-online I don't see why Tales would do it.
Are you sure the DLC is actually downloaded to the console? Maybe if you access the DLC through the USA account then go back to the EU account it'll work... I don't know. :<
