Issues > Always Show On Timesheet - only working when work has been logged for at least one issue

I have several issues that i have set to 'internal' and 'always show on timesheet', but they are only shown when at least one work log exists for the period of the timesheet. In this case i am using the 'User Timesheets > Weekly' preset.
Your documentation states that they should be shown even when no work has been logged yet. Is this a bug or have i configured/misunderstood the working of this feature wrong.
We would like to have the issues shown even when there is no work logged yet.
