Comet stacking help! Red and blue channels almost empty, green normal?

[ONIKKINEN]

As the title says, stacking with the align comet and stars option in DSS leaves red and blue channels almost completely blank, whereas green is present as i would expect it to be. Subs are not missing red or blue component and stacking in other methods (only stars, only comet) results in all 3 channels being there. Any ideas on how to fix this?
