GRUB doesn’t have the timeout anymore

I noticed this first when I removed the i386 kernel and left in place the amd64, so I installed the i386 kernel again, still doesn't work. Nothing explain why I need to select the boot option if I have the GRUB_TIMEOUT option set in the grub configuration file:

➜  ~  grep -v '#' /etc/default/grub 
GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX="initrd=/install/initrd.gz"

grub.cfg

➜  ~  cat /boot/grub/grub.cfg

I tried purging grub, removing the grub.cfg file, changing the GRUB_DEFAULT=0 and nothing improved.
