It looks like you put the same text at both your userpage ( <a href="https://wiki.roll20.net/User:891100" rel="nofollow">https://wiki.roll20.net/User:891100</a> ) and the page "Building a dungeon" ( <a href="https://wiki.roll20.net/Building_a_dungeon" rel="nofollow">https://wiki.roll20.net/Building_a_dungeon</a> ). Then you put your userpage in both the Tips and Guides categories, and tried to put your article in the Tips category, but did so incorrectly (the category link is wrapped in <pre> tags). Your userpage is meant to be about you, not an article. I've gone ahead and copied your bio to your userpage, and fixed the categorization on the article you created. I also cleaned up the wikitext formatting in the article a bit.
