Drice Wiper and Wipe Free Space in Options/Settings are separate processes. In Drive Wiper just carry on and wipe whatever you have selected.
The Options/Settings process is the original method of wiping free space that has been retained. It has fewer options than Drive Wiper and has to be executed by checking Wipe Free Space in Cleaner/Advanced. In this way it becomes a component of the general 'cleaning' procedure. It is independent of Drive Wiper.
In Options/Settings the Wipe Cluster Tips and Wipe Alternat Data Streams are part of Secure File Deletion: they are not part of any wipe free space process.
I don't think this is misleading, but it has caused confusion from time to time.
With Drive Wiper one doesn't have to fiddle with extra settings to enable/disable either such as having to remember to enable/disable Wipe Free Space under CCleaner's Advanced section. Although I'm so used to using the original Wipe Free Space I've personally never bothered with Drive Wiper other than using it once and thinking nah.
