Nah don't feel stupid. Those test strips are pretty notorious for being inaccurate. I'd try and get your hands on the liquid tests, they usually wield better results. Your trates look to be about 20 which isn't unreasonable. I'd do a water change and see if that helps them open.
Good luck! Just remember everyone is a beginner and some point and I don't think anyone can say they have never messed up before. Everything is a learning process in this hobby.
