Changes to zone files passed in via source="puppet:///path/to/file" aren't applied on agent run

[mlow]

Am using r10k and fairly new to puppet. Not sure if this is by design or not, but it's not very desirable.. I'd like to be able to update a zone file in the r10k repo, re-run the puppet agent and have zone fliles get updated as appropriate and the bind9 service reloaded so they take effect
Message I get from puppet when the existing zone file in /var/cache/bind differs from what's in the r10k repo:
Notice: /Stage[main]/Profile::Bind/Bind::Zone[128.10.in-addr.arpa-private]/File[/var/cache/bind/128.10.in-addr.arpa-private/128.10.in-addr.arpa]/content: audit change: previously recorded value {md5}f7c21a5814843e3e0b1c4c8fea261127 has been changed to {md5}6b460458483d62ddabf0722a9dd63292

But no changes get applied..

Needed to set bind::zone dynamic to false -- oops!
