CAA SERVFAIL on subdomain

I was guessing yourhosting.nl is using PowerDNS, allthough a query did not show that:

monitor@xs9:~$ dig +short ns wooncollege.nl
ns4.firstfind.nl.
ns5.firstfind.net.
ns3.firstfind.nl.
monitor@xs9:~$ dig +short version.bind chaos txt @ns4.firstfind.nl
monitor@xs9:~$

And pdnsutil rectify-zone does not seem to be a thing a normal user can do. Or am I mistaken?
