I cannot find the machine settings from Lightburn software

After installing a new X-tool D1 pro 20W, the laser will only frame and return to home. The laser never fires. I discovered the machine settings selection, under edit has disappeared. The Settings and Device setting selections are still there. How do I get back the Machine settings ???. I was already using and X-tool extended laser on this computer and everything was working fine until I installed the second laser.
