You seem to have skimmed over the "Buddy" section.

Alongside your Flag, which doesn't count towards the 50 card minimum of a deck, you also have 1 Buddy card that is excluded from the maindeck and isn't counted against the 4 copy maximum. Hence why the main cards in said Trial Decks are included in a number of 5: One for the Buddy Zone, 4 for the actual deck.
