How to clear detailed threat analysis icon on console under health state column

After upgrading our SEPM to SEP12 RU6, we are noticing a few clients that have a new icon in the Health state column that looks like a text and magnifying glass. After clicking on it , it displays "Detailed Threat Analysis" report with risks/virusses that the machine had almost 2-3 months back. Is there any way of clearing this as the machine does not have any more risks/events logged for it? By the way, the clients are on RU4MP1 so I can't do the Power scan analysis option...

Any ideas?
