Threat Detected - Malware and PUAs - Not deleting

Sophos has been installed on one of our storage servers, its come up with a lot of errors and warnings in volume shadow copy locations. I have since excluded these locations but it will still not clear. 

If I click resolve nothing happens. If I go into Sophos Central, all I can do is acknowledge, which I have done for all of them, but the error still displays. What can I do to fix this?

Thnaks.
