Backup not working - KDE Plasma 20.04

MY saga with backup continues...

I have this cron job, intended to run once daily and keep 7 versions, one per each day of the week

Code:00 18 * * 0 rsync -r /home/alex/afolders/ /media/alex/Elements/sun/
00 18 * * 1 rsync -r /home/alex/afolders/ /media/alex/Elements/mon/
00 18 * * 2 rsync -r /home/alex/afolders/ /media/alex/Elements/tue/
00 18 * * 3 rsync -r /home/alex/afolders/ /media/alex/Elements/wed/
00 18 * * 4 rsync -r /home/alex/afolders/ /media/alex/Elements/thu/
00 18 * * 5 rsync -r /home/alex/afolders/ /media/alex/Elements/fri/
00 18 * * 6 rsync -r /home/alex/afolders/ /media/alex/Elements/sat/Each line, runs when executed in terminal, but the job itself doesn't.

So, I tried to use the Task app in KDE. I setup one single task, just to try. Please see screen shots for my setup, theerror I get when I try to run it manually and the 3rd image showing directory structure - no rsync folder, so - where is it?

Hope someone will point out what is wrong here

Thanks
Alex
