Hi! Iim having the same issue. How was it solved?
All the settings of all tabs show in the first tab. Neverthless, I figured out the problem and solved it, I enter to each job post and had to select the field type ( it was heading preselected).
I already delete cached and even uninstall the cache plugin, but I still don’t see the fields. Also the options in the tabs in Job Board > Settings don’t appear. I only see the tabs, but when I click in one, nothing happens.
