Personal Roadmap creates incorrect filter

I have a project with 58 issues for a particular version. If I click on the Roadmap link it shows all 58 issues. If I click on the version label it creates a filter for me for the project/version, showing the same 58 issues. However, if I choose a personal roadmap it displays only 16 issues, which I assume is the subset of those issues which are assigned to me. Now, if I click on the version label, again it creates a filter for me, but it has forgotten to add the filter of assigned to current user, so I get the same 58 issues rather than 16. this is confusing. As an aside, I couldn't find any explanation of personal roadmap in your documentation. As another aside, I did a search on your doc'n just for roadmap and it found nothing, even though I know that is listed somewhere!
