SSL Chain issues – Contains anchor
Does your SSLLABS report mention ‘Chain issues – Contains anchor’?
Simple fix:
Remove the Root CA from the concatenated certificate file.
Use a text editor open your Root CA file as well as your Certificate file, check what the Root CA starts and end with and remove that section.

It is a last CA certificate in the chain which signs server cert must be removed.
If you remove Root CA certificate then you will end up with incomplete chain (B grade) on SSL labs test page.
to be specific, it is the self-signed root that is to be removed
