Reset default settings for “View by This Weeks Iterations” and “My Items Only”

When the “Project” filter is activated and the “My Items Only” filter is activated too the bold blue lines are shown within the Timesheet overview. As soon as I deactivate the “My Items only” the bold blue lines are gone, even though the workitems which are assigned to me are still shown. And when I now for any reason deactivate the “Project” filter the bold blue lines are sill not shown, but since the “My Items Only” filter is not visible anymore I am not really aware of the reason why the bold blue lines are not shown. 
Maybe it would be nice to automatically reset the default values for “View by This Weeks Iterations” and “My Items Only” in case that the “Project” filter is deactivated.
