Deleted files from PC are kept on MyCloud, Why?

Hello Everyone!

I’m having some issues tryinng to sync my files from the PC to My Cloud.
I have tons of pics and I’d like to have them on my PC and a copy on My Cloud device.
But whenever I delete/rename/modify I file on my PC I want it to be deleted/renamed/modified also from the My Cloud device.
When I modify a file, it is modified on My Cloud, but when I delete that file it’s not deleted from My Cloud device.
Why is that?

Yes, I’ve tried. That’s the software I’m using to sync things.
