The naming is really a non-issue because you can filter the gear by job.
There is a problem, however, in that the filters appear to be based on the items' job flags, which means you can't filter Ironworks and Shire accessories by job because all Ironworks and Shire accessories are "All classes". Rather than pursuing a localization adjustment, a more appropriate adjustment would be to make the UI filter gear by the jobs that are actually intended to equip them, so that, e.g., healers don't see casting accessories, even for levels that jobs would be allowed to wear the wrong accessories.
This, however, is still not the real issue. At its core, the problem is that pre-ShB accessories are still "All classes", allowing jobs to equip the wrong accessories. The best fix would be to restrict all post-50 accessories to their intended roles. Then we wouldn't need a localization adjustment or a UI fix.
