I have no idea but this is going to be a gorgeous quilt! Are all the measurements are the same for the depth of each row on this pair? It looks like the pentagon in the top right of the bottom row isn't oriented the same way as the one on the left side. Cutting one side too short can throw this kind of pattern off badly. It is likely just the camera angle making it look wonky but double check the measurements of that piece. The second row on that one on the bottom right (that starts with maroon) looks shorter than the second row on the bottom left (that starts with pink), too. Again, could be camera angle or not as flattened out.... Good luck!
PS counting lines on the mat, the one on the bottom right is at least an inch shorter than the one on the left.
