Board Game Arena

Hello. I won Farm Club yesterday, I still don't understand how I instantly completed one of the objectives (my second last card). https://boardgamearena.com/table?table=267060279





My understanding was that the 3 animals needed to be on the same row or column, here, I only fulfill either Horse+Pig or Horse+Chicken. Is it a bug or that just merged column and row as I do Horse+Pig and Horse+Chicken = Horse+Pig+Chicken ?
I took it thinking I would just discard the very last objective and swap a chicken and a pig on the very bottom row to complete it but instead it just gave me the points on the round I got the objective card.

Help me understand.
I would still have won without completing it seeing the 2nd player scored 22 points but still.

Thanks in advance.

It must be a bug with that particular card. I also scored and I didn't have a single horse! https://boardgamearena.com/bug?id=64558

Super interesting. Thanks. I assumed it bugged because I had all three animals across a row and a column but you didn't even have a horse.
