2 light spots on the laser beam

When I burn something on wood or anything I noticed that I have 2 light spots. Does that mean anything and how od I solve the problem. I think I have it focused with the smallest dot I can get. I have
an Ortur LM@ with a NEJE module.

which neje module?

A picture would allow us to ‘see’ what you are seeing. That would be much more beneficial for us to help you.
