Nameserver & dns Propogation issue

Yes i follow all the step of configuring domain and custom domain also i added nameservers according to docs but issue is still there,

In docs there is mention if i add a wildcard domain then nameserver will show on the vercel but i am not getting nameserver on vercel ,

I add all dns record that given by vecel then after sometime “qviq.io” and “www.qviq.io” become valid configuration but for custom domain when i add vercel nameserver all become invalid configuration
