Sticky images after Process for Cnc

i have still processd forms in luban after i worked with 3 svg files for cutting one after another.
luban takes all 3 layers allways even after reinstall the images are still there.
i did tht befor with no problems.

If you mean the CNC mode in Luban, you should be able to click on the image and press the delete key or right click and “Delete Selected Model”.
