I don't understand why I am on the list of unreliable crowns, and why it says that I signed an NAP with Jiub.

When I took Spain, I said from turn one that I cancel all unannounced NAPs and agreements with all factions. If I ever had an NAP with
the Moors I didn't break it, if anything it was removed by both parties and 'transformed' into an alliance.

As for Jiub, if he believes I had an NAP, I want to know. I can't attack someone I have an NAP with unless he breaks it by attacking me or my pre-NAP ally, and in all cases this is breach of the non-aggression pact.
