Recently Deleted is my PC's Recycle Bin??

I am trying to find a file that I think I deleted out of my Creative Cloud folder. I logged into my account through the browser, went to Your Work > Deleted Items, and started to search for the file. Imagine my surprise to find a significant number of files that have NEVER been in my CC folder. Why does Deleted Items now mirror my computer's actual recycle bin? There is NO reason why the two should EVER sync. Who came up with this??
