I just played two-player Euchre for the first time. Twice when I was not dealer we both passed and I was given a choice of two remaining suits for trump rather than all three (that weren't the suit of the turn-up card). Is there a rule about this, or is there a bug? I couldn't find it online. Thanks!

BGA cutthroat Euchre allows selecting suits you have only (or no-trump if enabled) during the second bidding round, because selecting other suits doesn't make sense in cutthroat games.
