Problem - All grub kernel options not showing?

Had a load shedding issue that hit my college building at 2am and building
generator didn't kick in, and UPS didn't say up for the hour outage. Went in at
about 6:30am on Sunday to fix things, and found that one of my main servers
was coming up with the grub menu, but only the options for memtest and my
g4l special option were showing up. None of the kernel option would show
up? After booting with the g4l option with its kernel, I was able to look at the
grub.cfg file, and options are there in the grub.cfg file.
I was able to get it to load the kernel by copying the kernel options to the end,
and removing the extra stuff after the menuentry name?? I had also
commented out the load_video line, and switched, the linux16 and initrd16 to
linux and initrd, but don't think that was the issue, since after doing a reboot,
it wouldn't show the opiton until I changed it to just
menuentry 'Fedora' {
I though it might be the blkid that was off, but it seems to be correct.
Below is the current grub.cfg that I had made on the machine using
grub2-mkconfig -o /boot/grub2/grub.cfg
Originally, it went thru, but the reboot showed only the memtest option, and
the g4l option, and I did the coping of the line, and modification to get it to
boot.
Had a 7am meeting that I ended up being late for, since I could get the
machines all up quickly. Machine is now running, but still don't know why the
regulare grub menu options are not showing. The 20+ other machines seem
to have the grub working just fine. This machine did recently have a
motherboard failure, and it was replaced, but everything else was the same.
Below is the grub.cfg and the output of blkid??
Thanks.
