Yes, it is duplicate that is already fixed.
https://github.com/yast/yast-bootloader/blob/SLE-15-GA/package/yast2-bootloader.changes#L39

Sadly leap 15 contain this bug and as there is no self-update, it cannot be
changed. But already fixed for leap15.1 or any media that is build from Leap15
sources with updates enabled.

Thanks for report.
