[SOLVED] Ticket behavior in the Timesheet whether it or not assigned to a parent activity

Hi all,
A Ticket belongs to a project but can be linked to an activity or not.
The question is about the way a Ticket appears in the timesheet.
In case a Ticket is linked to an "parent activity" it appears as belonging to the project and this is OK.
But in case the ticket is not linked to an activity it appears as a "not assigned work" and does not appear within its project and the way I understand it this not correct.
Can you please explain why is this behavior
