Even if "Enable system monitoring" -> "Automatically clean without notification" is checked I still receive a popup message asking me to clean the system.
I think this happens in the last 2 updates.
Sounds like you're using a Pro version of CCleaner, so you can get in touch with Piriform directly by sending an e-mail to support@piriform.com
Well the monitoring is in CCleaner Free too.
If you're using CCleaner Free, see here for the settings of it:

But you can't select "Automatically clean without notification" in the free version
