you may have the time grub displays set to zero

sudo nano etc/default/grub

GRUB_TIMEOUT=0

or have the prober turned off

GRUB_DISABLE_OS_PROBER=true

change to suit your needs, then

sudo update-grub

personally I have

GRUB_TIMEOUT=2
GRUB_DEFAULT=saved
GRUB_SAVEDEFAULT=true

which (if no user interaction) runs the last OS choosen
