Insert and Format not visible in Ribbon

Question

So we've got a SharePoint 2013 Publishing site that uses custom master page, page layouts and content types.    Each content type uses a number of 'Full HTML content with formatting and constraints for publishing' columns. 
However, when users attempt to add content to these columns on a page, they are unable to see the Insert or Format Text ribbon tabs.
What have we done wrong to prevent these tabs from becoming visible?

Hi Arcanedevice,
can you try to add the below script on your page to make visible the Ribbon Tool bar.
you can try to add using content editor webpart on your page or list form by editing the page and add webpart.
<script>
setTimeout(function() {
var elem = document.getElementById("MSOZoneCell_WebPartWPQ4");
if(elem != null) {
var dummyevent = new Array();
dummyevent["target"] = elem;
dummyevent["srcElement"] = elem;
WpClick(dummyevent);
}, 100);
</script>
give it a try and let us know if the issue is still persist.
