Disk Space not freeing after remove Parallels Desktop Device

[calvincty]

Hi all,
Recently just purchased and installed Parallels Desktop, have tried install several device and removed due to some issue.

However I've noticed the disk space is not reduced even though I've remove all the virtual hard disk, devices or uninstall parallels desktop using CleanMyMac2. Trash is clean as well.

I checking the disk space utilized using Activitiy monitor, and also Finder, both showing the disk space without reducing after removal of parallels dekstop. But something weird is that when I checking "Get Info" on the drive, it shows the reduced space.

Current occupied space is 139GB, showing in both activity monitor & finder, in "Get Info" of the drive only showing 79GB is occupied. Any idea what is the problem of this?

I'm using Fusion drive of 120GB SSD + 500GB hard drive.

This is the screenshot https://www.evernote.com/shard/s77/...7108eb459fe0/e04f6a80a253b406b0a7fa8323aebf5d

Hope anyone here can help.

When I'm using Omnidisksweeper to check for the disk space, it shows only 88GB disk space has been used.

I wonder is this something like cache or what? no idea
