I am adding a custom report to v16 and when I add a new criteria i get the following error message:

"The value for UpdatedDateTime property in the request doesn't match the current UpdatedDateTime for the resource. The resource might have been updated since you last retrieved it. Please get the latest version of the resource, merge your changes and try again."  I am the only one working in the resource and have not changed anything.  Have relogged in to Tessitura.  Tried adding a different criteria - nothing seems to work.  When i save with just the original criteria it saves.  Any help would be greatly appreciated.  Thanks
