As seen in the link when you hover over the custom column titles they do not show up after the last update. The other problem we have is the “more” for the read more is blocky and the triangle design overlaps the text and looks terrible. How do I fix the “white block” titles so you can actually see the titles and how do you get ride of the terrible new “triangles” beside the “more?”
