Hello David,
Thank you for contacting CA Agile Central Support regarding this case. I'm sorry that you are having problems with the Iteration Status page. We have seen this issue on occasion and have been able to resolve it rather quickly. Could you change the "Show" number at the bottom of the page, re-sort the list by ID or Name, then sort again by Rank (by clicking on the column names), then change the Show number one final time please? We have found that this permanently fixes the issues for users. Please let me know if this fixes the issue for you.
Regards,
Julia Giancola
