/etc/grub2.cfg Flagged a Potenially missing

Hi,     /etc/extlinux.conf is flagged as missing, the file is displayed in red and the link is shown in white text on a red background. As mentioned in another thread on this list that file actually is missing.     /etc/grub2.cfg and /etc/grub2-efi.cfg both of which point to the same file also display the same way as /etc/extlinux.conf, but in this case the file pointed to actually does exist, and is linking to /boot/grub2/grub.cfg, which I regularly write to with sudo and grub2-mkconfig, but I have also found that I need to use sudo to browse /boot/grub2. Is it normal for links to be flagged as missing when sudo is required to list the contents of the directory and why is sudo required to list the contents of /boot/grub2 when I don't need sudo to list the contents of /boot? /boot/efi seems to be in the same situation. regards, Steve
