SWON Still Visible in Timesheet After Release – What Does It Mean?

My SWON ended on 3rd June, and I was released from the project on the same day. However, I can still see that SWON in my timesheet, even though it was only valid till 3rd June. Why is that?

Also, after my release, a non-billable time slot has been created in the 'Assigned Task' section. I'm currently on the bench. What does this mean?

Will this have any impact on me in the future? Can I still fill timesheets under that SWON?
