PO release strategies ,all release statuses are not manageable

Dear all,

I try to create a PO release strategie with 8 release code . I managed the release prerequisites (one code is mandatory) but when I try to manage the release statuses , I just have a windows with 17 entries . How can I manage the all combinations ?

(When I save the strategie , the table T16FK has 129 entries)

Thank you for answers , BR , Philippe
