CL-Kernel not updating grub list

I left this question in another forum here, it was never answered. I would appreciate some help. Thank you.

cl-kernel does not actually ADD a kernel grub entry. I would like to keep on adding kernels, with the list growing larger and large. CL-Kernel seems to have a max menu entry of 2 kernels (not including “safe”).

What am I doing wrong? Thank in advance.
