Exactly Chris! The same thing happened to me. I removed the HTML from my custom label & it then loaded fine. You'll also notice, if you export your report to a spreadsheet, the HTML tags show on the spreadsheet also :-/. I haven't submitted this "glitch" to NS yet, so IDK if they are aware of the issue. I just came up with my own internal rule... if it'll just be a report displayed online only, i'll use html tags... If i believe the person may download the spreadsheet or use it as a dashboard, I omit HTML. Sucks.
