Board Game Arena

According to Pagat, "A prime (aka premiera) consists of four cards, one of each suit." But on the BGA wiki for the rules https://en.doc.boardgamearena.com/Gamehelpscopa it does not say this and, in fact, shows a "prime score" example with only three cards (and, strangely, uses the Jack of Clubs when the player captured the 7 of Clubs which is worth far more points.)

Does this game only score a Premiera when the player has at least one card in each of the four suits? Is it an error that the BGA wiki gives an example where the Jack was used for the Clubs card?
