Because the original menu's built with "grub2-mkconfig ..." and later
kernels are added by grubby.

Because grubby duplicates the previous entry's "Loading ...", although
it also gets it right so the grubby developer's (if it's grubby's
fault) going to have some fun tracking this down. There already a BZ
that someone posted earlier.

> - no rescue mode menu entry for the kernel-PAE was created

Because grubby only creates one entry when a new kernel's installed;
"grub2-mkconfig ..." creates a "regular" entry and a "single" one
(unless you change that default behavior in "/etc/default/grub").
