Are you sure that's constructed properly? There's usually a precise
structure for zone files. All examples I've seen have things in this
sequence (just the sequence, I've not typed in all the data):
$origin .
$TTL
SOA (
serial
refresh time
retry time
expiry time
minimum time
)
NS
A
MX
followed by the rest of your records
I'm not sure about where you might add a new thing, like CAA, but I
wouldn't rearrange the order of that other things without being sure
about it.

Yes, anything you put left of IN A, that doesn't end in a dot, is a
sub-domain (the server appends your domain name to it).
