It is normal for clients which don't support SNI (server name indication) and SSLabs tests what happens in such case.

Depending if you need to server web for old clients (like Android 2.3.7, IE 8 / XP, Java 6u45) the only way is to set up a separate IP (both ipv4/ipv6) for each domain, if not - you can ignore the MISMATCH error (also it doesn't impact the SSLabs rating).
