This bug exists in ubuntu installer at least for 3 years. Only now I have overcome my lazyness and submitted it.

I take it you have repeated the process to make sure you selected the correct drive? Have you tried manually running grub-install?

Yep. And when it fails to install it presents a dialog to try again, but result is the same.
I had to ignore this error, finish installation and in chroot evniroment run:

grub-install /dev/mapper/isw_ebhcfihceg_SSensitive
update-grub

By the way - partition table is also displayed wrong - examine UbiquityPartman.txt. I have two devices with Storage and Sensitive.
But it displays their partitions as additional devices. I think this is source of a problem.
