I took a double look at your lay out, it looks like you have one on the line, and the other not quite, you may want to remeasure them. They may just look like they are different sizes. But then again I am the queen of never the same size twice or even once. I cut real careful, sew as careful, and never end up with the size block it says its suppose to be so close enough is good enough for me. lol.
