That is what happens when you don't use enough variety in your fabrics. You can probably work it out because the app doesn't see that two of the same fabric are next to each other. It would drive me nuts so that is why I always use a lot of different fabrics when I make a scrappy quilt. Did a Yellow Brick Road and I was literally changing a fabric in a few blocks. I know I have this problem so I have learn over the years how to avoid my problem.
