Autocreate RFQ from requisition - why requisition still displayed at Autocreate form?

Dear All,
I have a question concerning Auto-crate form usage,

When auto-create a RFQ from a specific requisition line, the requisition line still displayed at Auto-create form?

Clarification:-
when create RFQ from requisition through Auto-create,
then create Quotation from RFQ through copy document,
the PO was created from Quotation  using Copy document,
the requisition still appear at Auto-create form.

Best Regards
