404/301 SC Easy URL Redirects

it Did'nt it work for me? i tried 3 times and reached out to help for support, but unfortunately, no help.
I tried a bulk upload 3 times and each time it ignored the redirects so on the 3rd time I checked the box to over write all re-directs and this time it did not ignore them. BUT after testing some of them still not working and going to a 404 error page. so 1 start from me.
