I use the Legacy system at BIOS.
Mageia 9 is only an alpha, and problems can be expected. If Legacy GRUB
is even available, don't use it; use Grub2. Grub2 has a thing called
os-prober, which looks for other distros, so it needs to be active. In
/etc/default/grub, I have a line:
GRUB_DISABLE_OS_PROBER=false
If that is set to TRUE, it may be the cause of your problem, but I doubt
it; it never is. File bug reports.
I found out what was wrong. Mageia 9 was installed on a GPT partitioned
disk. I erased the entire disk and partitioned it MSDOS style.
How unfortunate. I partition all my drives as GPT.
That allows me to Partition Label and Name all partitions.
I then use the Name to mount everything and can re-format and move partitions around without having to modify /etc/fstab.
$ cat /etc/fstab
LABEL=cauldron / ext4 relatime,acl 1 1
LABEL=accounts /accounts ext4 relatime,acl 1 2
LABEL=BOOT_EFI /boot/EFI vfat iocharset=utf8,umask=000 1 2
LABEL=local /local ext4 relatime,acl 1 2
none /proc proc defaults 0 0
LABEL=spare /spare ext4 relatime,acl 1 2
PARTLABEL=swap swap swap defaults,nofail 0 0

Using Partition Label and Name also makes it easy for scripting disk work and to see/find where everything is located.
