In the past, Bubble used to give two specific IP addresses, so my records have two A name and two www settings. Now it looks like Bubble only gives one, so you would only need two records: one www and one A name.
If any domain is not sending you where you expect, you can Google for check DNS online and use any of the online tools to check your DNS records for an external observer.
Also check on your DNS to make sure there are no www or A name or CNAME records that were previously present and may be conflicting.
