Lightburn not turning on the laser

I installed lightburn to use with a MPCNC with a 40w laser diode module. the machine is running marlin and it uses M3/M5 to control the laser, which i can do through pronterface without issues. If manually add a marlin laser i am able to move the machine, but the laser doesnt turn on and “laser control settings” in device settings are disabled, so i cannot tell the software to use M3/M5. If i instead add a device from the wizard it detects my machine as a GRBL-M3 1.1 one, and if i try to send a cut it says:
“Transfer failed
There was a problem sending data to the laser
The machine may be busy or paused”
I have been looking arround but i was not able to find any fixes. Please help

In what way is this disabled? The controls might be hidden if your screen resolution is slightly atypical or your font size is different. Increase window size if required.

Should look like this:

It was exactly that, thank you!
