These links illustrates the problem.. https://github.com/jenkinsci/jenkins/blob/08def67a18eee51de9f3f99bc2a792fee1c160e0/core/src/main/resources/hudson/model/AbstractProject/sidepanel_es.properties#L26
Workspace is "Zona de Trabajo" (zone of work) but wipe out workspace translates it to "Espacio de trabajo" (space of work).
… Workspace is translated to "Espacio de Trabajo"
So, it's possible to see a different translation in the sidebar than in the main area for the same link!
The inconsistency seems to be introduced @ https://github.com/jenkinsci/jenkins/commit/68890bb641cb587b7b73b032310b2a725a05c3ec#diff-53fa0fa898ac0055eca29d2566b90e62R28 which just says "community contributed translation"
