Unable to select sandbox certificate to my provisioning profile

Dear All,

I am facing issue while creating provisioning profile with the certificate which has APNS service enable. I am able to Register new “Identifiers with my new bundle id and all required cabability” . Also able to create certificate with Service for (Sandbox and Sandbox & Production) During the creating the certificate, I am able to choose my newels register Identifiers.

Now my issue is When I am creating the Profile for same , I am able to choose my identifiers but unbale to choose the certificate (which I have created for APNS).
