Why does CCleaner ask to close Edge Chromium before cleaning?

The only browser I ever use these days is Google Chrome, mainly because I used to use Firefox, and found it cumbersome and filled with ads. It's not perfect, but Chrome just seems smoother.

My question is...why, when I'm shutting down at night and want to use CCleaner (free version) before shutdown, does CCleaner ask to close Edge Chromium, and then ask to force close it, when I never use Edge, (though it is installed as an alternative browser)?

In Chromium Edge go to 3 dots (top right) and select Settings.. System and make sure 'Continue running background apps when Edge is closed' is unticked.

Thanks
