How do I edit the default text in Jobs & Experts?

Hi there,

I would like to change the default text in Jobs & Experts to Jobs & Contractors. I tried using PoEdit to 'translate' the language file, making the text changes, then saving new jbp-en.mo and jbp-en.po files, but when I uploaded new files to language folder,nothing changed.

I'm not clear on how to go about this. Can you please provide some assistance in how to edit the word Expert in the plugin and change to Contractor.

Thank you.
