PPM Item DPs & Project Phases are copied twice

Hi All,

My Portfolio Decision Points & corresponding Project Management Phases are copied twice in Item level.

for example: I have two Item types 1. NPD-Proposal which gets changed to 2. NPD- Development also at new Item type NPD Development we can create a Project. Once the project is created the Item Decision points and Project Phases are visible twice at Item initial screen

please see screen shot for more details, please let me know as what is wrong ...

At Decision Point 'Design Inputs', we can change the Item type from NPD-Proposal to NPD-Development

Thanks

Yasar
