Workout app not including all the weights

I recently started using the Workouts app. First and foremost, like Macrofactor, it is phenomenal. Truly incredible and beyond anything I could’ve imagined. I love these apps.

Just one question: when I downloaded the app, it asked me to put in all of the gym equipment I have (in my garage gym). I put everything in exactly.

I’m doing a workout now and it suggests plate orientations for me when I put in how much weight I’m using, which is again a truly incredible feature, I’m amazed. It always calculates the plates on the bar correctly based on what’s available to me.

But today it made a mistake for the first time. It kept telling me that I was 15 pounds short of the number I put in, but I had two additional 7.5 pound plates. And I put into the app that those plates exist. I guess I’m not sure why it didn’t just add all the plates like it usually does in the suggestion?
