Adding layers to a cam job

After importing a .bmp to the PCB, EAGLE place the bmp at the 203-209 layers, missing 200 where really it is the image.

With this command “change layer 200”, i finally can view the image on the PCB, but, when I’m going to process the job to obtain the Silkscreen, the layer 200 is still missing.

Do you know how to add an extra layer in the CAM menu?

Or how can I swap layers? for example 203<->200 (change layer doesn’t work as I can’t select the image on the pcb u_U)

Solved, I’ve just had to restart Eagle (2 times? xD), it seems a bug.
