Stop getting LTAZ6_ prepended

How do you get Cura to not prepend :LTAZ6_ at the beginning of the file name?

There is so little room on the small LCD screen on the Taz6 and this just pushes the meaningful part of the file name off the right side.

Preferences > Configure Cura > Uncheck “Add Machine Prefix to Job Name” under opening and saving file options.

Thank you!
