first of all, you need to clarity the exact name of the planning tool you are using. requisition worksheet and planning worksheet are similar but not the same tool. I doubt that you use both for planning cause that will confuse the system.
If you are not on premium license with no production, then you are using requisition worksheet.
check the line no. 3000 on the worksheet what item it refers to. if an item is reserved, it must be reserved for a demand, be it a sales order, production order etc. To effectively determine what to plan, when to plan, BC needs the due date.
go the item card and check reservation entry, complete the reservation by populating the due dates if missing. Also, you could use order tracking to trace the origin of the reservation.
also check the reservation setting on the item card, update as needed.
those might help you further troubleshoot, hope it helps
