Why cant see associated issues in project roadmap version list in Jira on demand?

I have created software project with versions and associated issues to version, but if i look at project roadmap(project->overview->roadmap) then it shows version number and its description but doesnt show associated issues...

if issue tied with roadmap using "Affects Version/s:" field then it doesnt appear in roadmap, if its tied using "Fix Version/s" then everything ok
