Why certain domains is not propagating?

I have a total of 5 domains in my droplet setup the same exact way, but only 3 of them is working correctly. I have been having a hard time getting 2 of my domains propagating to all servers.

So I’ll use one of them as example for this post.

As you can see there is a few servers that does not want to propagate. I sent a support ticket to digitalocean and all they told me is that “It’s a propagation issue” which hasn’t helped me solve the problem.

Note; I added this domain to my droplet a week ago and it has been more than 48h, plenty of time to propagate. My other domain tha tis not propagating correctly has been more than 3 months

Other domains that is working on the same droplet configure the same exact way:

This is driving me nuts for a long time, what could be happening here? Any help to point me to the right direction will be highly appreciated.

Thank you!
