CA and Certificate generated is not valid when imported into Windows

I am trying to create a CA and respective certificate in Beta 2. Once generated, I am importing both these files into windows certificate store (in the trsuted store). However i am still getting SSL / certifcate errors. The screenshots are attached below for the settings that are being used. I can attach the certificates privately also if needed.

Screen 1 - This is the "CA's" page option when a new CA is to be created

Screen 2 - This is the "Certificates" page when a new Certificate is to be created

Screen 3 - This is the cert invalid image after adding the CA and Certificate from above to the Windows Certificate manager (under Trusted Root Certification Authorities part)
