It's not normal you see 3.3.7 listed as latest, since that is read online, and the only version we have online is 3.3.9 (and before there was 3.3.8 ). If you see 3.3.7 as latest, it means your local cloudflare node is still not updated, which is not normal, since 3.3.8 came out last week, they usually take from a few minutes to a few hours to update everywhere.
If you can try with a VPN, so you'll connect to another node, it might show the correct version. If you can't, just use the OFFLINE installer.
