Hello,
1) Could you provide link to page where you use that element for better understanding of the problem?
2) All departments text is the text of the secondary menu http://prntscr.com/nv0igb I don’t see that the secondary menu is enabled on your site. Could you, please, tell me do you want to translate this text at the backend or on the fronend? Provide screenshot of the source text that you want to translate, not the text in the string translator.
Regards
