Looks like there are some discrepancies with the delegations which might
be the cause of the problems:

https://dnsviz.net/d/25.233.82.172.in-addr.arpa/dnssec/

    172.in-addr.arpa to 233.82.172.in-addr.arpa: The following NS name(s)
were found in the authoritative NS RRset, but not in the delegation NS
RRset (i.e., in the 172.in-addr.arpa zone): ns-261.awsdns-32.com,
ns-653.awsdns-17.net, ns-1527.awsdns-62.org, ns-1856.awsdns-40.co.uk

    172.in-addr.arpa to 233.82.172.in-addr.arpa: The following NS name(s)
were found in the delegation NS RRset (i.e., in the 172.in-addr.arpa
zone), but not in the authoritative NS RRset: a.ns.campaign.adobe.com,
b.ns.campaign.adobe.com, c.ns.campaign.adobe.com, d.ns.campaign.adobe.com
