A Records. You should have two A records. Both need a host name of @ and the two up addresses are: 75.2.70.75 and 99.83.190.102 so remove the www A record and replace it with a second @ towards the other IP.
Trailing dot. Some DNS hosts require trailing dots at the end of domains. You will need to add a . After the value of your CNAME record.
Default domain. The default domain in Webflow needs to be the www version. Click make default next to that and then remember to Publish your site again.
Those three things should fix you up.
Cheers!
