Yes. There is only one rescue initramfs created, so you have to delete
one to get a new one.

To know for sure you need to debug it. I think bash -x in front of
new-kernel-pkg may work to expose the exact grubby command used. Then
you use that same grubby command manually, but add --debug flag and
see what it's complaining about.
