X & Y axis not jogging

I need help. I used my cnc 3018 with Lightburn yesterday for a project. Worked fine. Today…, my X axis does not want to jog left and Y axis not jogging backwards. I tried it with Lasergrbl and my offline controller…, then works fine. The problem is with Lightburn. I did not made any adjustments on my LB settings, and cannot find any LB setting related to this problem.
What am I doing wrong…?

This happens when I set up laser position before burning. When actually burning a project, x and y moves normal.

Sometimes this problem occurs to me too. I solve this problem by performing homing.
