Why is the first predicted issue generating with the second combined month twice: 2015:Sept.-Oct.-Oct ?

Answer

To correct click: Tools > MARC21 Holding > Next Predicted Item’s Information and edit the second level of chronology(j) field. It will contain a combined issue, for example 09-10. Change this to a single issue, for example 09, and the predicted items will correctly generate.
