After upgrading v4.33, the custom actions in popups don't show up when clicking on the '...'

The array is I'm using to populate the actions are this simple format
buttonOptions.push(
{
id: "actionLinkToReport",
image: "img/reportPDF.png",
title: "History Report"
});
The CSS for the popup appears to not be working properly after I assign my actions to the popup, can someone from ESRI please take a look or provide a proper example for usage?
