Cannot modify this header

I have tried editing the headers through “Highend Options” -> Font Settings, but for some reason I can’t edit this header written “Andokope K-JSS School Complex”. This is a portfolio item and I can’t seem to edit the header for any of these items.

Also, how does a user know which headers “header 1, header 2, header 3, header 4” is referring to on the page? Every time I go in to change it, I need to check back on the web page to see which of the headers have been changed.

Thanks!
