Cannot Select free space only on the Drive Wiper

I am using the latest version of CCLEANER Pro. Use the free space wiper option on the tool Drive Wiper weekly. But now the software does not have the free space option available to select? Anyone else have this problem and how did this happen and how to fix it please?

When I reinstalled it, the free space option came back but then a day later, the option is gone again.
