Cut the triangle again instead of the square

I have an S1 and am currently using Lightburn 7.03. In previous forums, there was lengthy discussions about this issue and last May, it was posted that the new Lightburn version 7.0 would fix it. I cam using the current version, and my S1 is still cutting triangles when I put a square around a design to be cut. It finishes cutting the design and then starts the diagonal instead of the square. I have ruined multiple projects because of this bug, and agree with many other posters that XCS isn’t suitable for what I need.
