The edit button is grey on all the built-in or downloaded rhythm, how do I edit them?

user warning: Unknown column 'u.signature_format' in 'field list' query: SELECT c.cid as cid,, c.nid, c.subject, c.comment, c.format, c.timestamp,, c.mail, c.homepage, u.uid, AS registered_name, u.signature, u.signature_format, u.picture,, c.thread, c.status FROM comments c INNER JOIN users u ON c.uid = u.uid WHERE c.nid = 17 AND c.status = 0 ORDER BY c.thread DESC LIMIT 0, 50 in /home/scienceb/public_html/tivstudio/www/modules/comment/comment.module on line 992.

  The App by default protects you against editing any of the built-in patterns or any rhythm that was downloaded from the online database. Instead of editing it directly, tap the + button to add a new pattern, you can than make the new pattern a copy of an existing one (or blank) and edit that.
