Inventory reports two versions of iexplore.exe

Good Day,

Recently, we rolled a portion of our computers back from IE10 to IE8.  On some of these machines, the Audit Software Report (which looks at the audited file inventory) indicates that both versions of the executable still exist on the computer in the same location.  We have verified that this is not true, but cannot figure out why both versions are still being reported as present.

Has anyone encountered this issue or a similar issue?  Could you point us in the right direction of how we might be able to deal with getting this fixed?

Thanks.
