Maybe the nvl function can help you. It works like:

select nvl(my_col, '123') from my_tab;

Everytime my_col is NULL '123' is returned. The problem is I don't know if there is even a null value available. The other way is to create a dummy table containing names of months. Fill it with
a small procedure with all names of months lets say from 01/1997 to 01/2100 and use this table in your matrix report.
