This can be set with a partition editor, such as parted, or you can run livecd-iso-to-disk with the --reset-mbr option. Expected results: Correctly written USB drive. Additional info: Also happened on Fedora 25 before system-upgrade.
A quick glance tells me line 408, or something before it, is wrong - p=${p##$device} sets p and partnum to empty strings.
I have confirmed that livecd-tools-24.1-1.fc26.x86_64 does not suffer from this problem.
