Welcome to the community Nick.
Based on what I see on your screen capture, this seems to be localized to just one terminology on Workfront, all the others eg issues, More have not converted to another language which means someone who has access to setup>interface>layout templates>(select your PM interface template)>Terminology might have changed it. If you are the systems administrator to your instance, you might want to check that part out or if you have a sysad, ask them if they've been playing with it.
Cheers.
