I have an editor that I can't seem to get my custom tools loaded into correctly. The group and tools load (the custom events are working also), but the text on the tools doesn't. All I see is the groups, with buttons that have a gear icon on them (but the tooltips correctly show the text). Since the editor shouldn't have the custom tools in every user scenario, I left this part to be loaded in by the code behind and the rest of the tools are loaded by an XML file. Not sure if it matters, but I am doing this with the Ribbon appearance. And the aspx page is being rendered inside of an iFrame.
cs code (called from Page_Load)
