y2log for only the bootloader session

Trying to install a bootloader using YaST/bootloader

/dev/sda3 was used to create the boot prompt using openSUSE_13.1.  This one has
the option 'set active flag in partition table'.

Currently /dev/sdb5 with openSUSE_42.2 is used, I used the same 'set active
flag' check, to create the boot prompt.

The result is:
  y2log:Error output: /usr/sbin/parted: invalid token: legacy_boot

This seem to be caused by the 'set active flag in partition table' setting. 
When I removed the setting the setting, the bootloader creator finished....

Details in the attached log file, and screenshots.
