Help needed in understanding the reason of failure in PMI Audit

I am Kazi Noor Ahmed. I applied for the PMP exam and fall under the audit process. After a few days I got a mail from PMI stating that my application didn't pass the audit process and thus the application was closed.

Now I need some expert opinion to understand the reason of this failure.

I mentioned 8 projects for this application out of which 4 passed and 4 failed. The projects where I mentioned myself as a project manager were passed and all the projects where I was a project contributor were failed.

I am attaching my application and the audit report here.
