Problem with saved gcode

Export/Save Gcode for snapmaker 2.0 A350 latest firmware, there is a problem in the gcode, code M107 is generated in that code and when i open it in Luban software and burn the laser power is bad.
Editing the code and delete all M107 will fix and it burn with right power.
I can’t see what M107 is doing and why it’s there, is there some config to change for Snapmaker device to disable this.
