Hi! I just checked out the most current Org from git (1af215bb4668bf) and found out that with removing SCHEDULED or DEADLINE using C-u C-c C-(s|d) I get:
Entry repeats: DEADLINE: <2013-04-15 Mon +1w -0d> in the minibuffer line (example is from removing DEADLINE). The heading does not have any deadline any more and did never show a repeat. So this is clearly a bug from my point of perspective. -- mail|git|SVN|photos|postings|SMS|phonecalls|RSS|CSV|XML to Org-mode: > get Memacs from https://github.com/novoid/Memacs < https://github.com/novoid/extract_pdf_annotations_to_orgmode + more on github
