DNS ISSUES Virtualmin on digital ocean. Help!

I have setup virtualmin on a digitalocean VPS. Installation went smoothly and I choose the LEMP bundle.

I have added a domain name and domains seem to resolve to their appropriate virtual host but I have some dns issues that I don’t know how to resolve.

I want to let digitalocean manage as much of the DNS as possible.

When I check the domain on a DNS checking site I get the following errors:

All nameservers in the delegation have IPv4 addresses in the same AS (13335).
All nameservers in the delegation have IPv6 addresses in the same AS (13335).
All nameservers in the delegation are in the same AS (13335).

and

Nameserver ns1.digitalocean.com has an IP address (173.245.58.51) without PTR configured.
Nameserver ns2.digitalocean.com has an IP address (173.245.59.41) without PTR configured.

I thought digitalocean automatically handled PTR config?

How do I resolve these issues?
