we encountered the same problem. Even if the project name or request name is listed in the "Request" or "Projects" portlet,we didn't open the projects or request when we click on the IDs.
We found cause of the problem but this may not be the case in your situation. We realized that those projects are created by "Save Draft" option and not submitted yet. But there is no found solution to that problem.Only thing we did is to remove the "Save Draft" option from the configuration.
