DNS not behaving well anymore

Here's my OS:

Linux bradakis.com 5.2.18-200.fc30.x86_64 #1 SMP Tue Oct 1 13:14:07 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

Here's my named version:

BIND 9.11.10-RedHat-9.11.10-1.fc30 (Extended Support Version) <id:9390ecc>

Here's one of my DNS zone files:

$ORIGIN com.
wasatchfoodies 3600 IN SOA wasatchfoodies.com. postmaster.wasatchfoodies.com. (
2019070500 20800 900 360000 86400 )
3600 IN NS ns.wasatchfoodies.com.
3600 IN A 50.198.190.18
3600 IN MX 10 wasatchfoodies.com.
3600 IN MX 20 bradakis.com.
$ORIGIN wasatchfoodies.com.
localhost 3600 IN A 127.0.0.1
www 3600 IN A 50.198.190.18
ns 3600 IN A 50.198.190.18

And this:

[root@bradakis named]# named-checkzone wasatchfoodies.com ./wf
zone wasatchfoodies.com/IN: loaded serial 2019070500
OK

But if one goes to dnsstuff.com and runs a report on that domain it claims a failure due to no SOA record, and a failure due to no MX records. But it worked with this configuration file for quite some time, used to get no fails. And it is not just this domain, but all of them run from my server. I can not figure out what changed, why this is happening.

Any clues on how and where to track this down?
