From shared screenshot , that's no problem about Development Certificates ,you will see the private key after clicking the down arrow .And it shows Valid in VS from PC(THINKPAD2).

However , the Distribution Certificates can not seet the down arrow . You should be sure that this Certificate is created from a new CSR file Mac to generate the Distribution Certificates .You can not use other people generated CSR file or Development generated CSR file to generate a Distribution Certificates .

By the way , if certificates is in System Group , you can copy it to Login Group . Then it will show private keys .
