Problem with lpm_decode in Quartus 14

I'm trying to implement lmp_decode and I can't edit the number of eq outputs. In earlier Quartus versions, these values were edited in the Megawizard dialog. In v14 the new parameter editor is supposed to handle this. Indeed, it does have a field called LPM_DECODES which is for specifying the number of decoded outputs but the drop down menu for this value only contains "2*LMP_WIDTH" and has no other values to chose from. When typing the value in manually, nothing happens. Regardless of changes made in the parameter editor, there is only one eq output. Is anyone else having this problem? Am I doing something wrong? Is anyone else using v14?
