I wouldn’t mess with your DNS records here…much.
mail should be DNS Only
ftp should be DNS Only
That’s because Cloudflare doesn’t proxy mail or FTP. But that doesn’t have anything to do with a Redirect for your website.
Considering you have the correct name servers, all evidence points to a previous integration interfering with your records.
Would you happen to still have hosting for your spirit website? You might be able to toggle that DNS record to DNS Only and handle the redirect at your host.
Otherwise, you’ll have to open a ticket here and see if Cloudflare can clear up whatever integration is interfering with your record(s).
