awslogs.config forwarding some logs but not other

On my EC2 RHEL instance I have the following awslogs.config in my /var/awslogs/etc directory. I'll cut out the top part and get right to the logging aspect in this code snip.

[/opt/apache-tomcat-8.0.26/logs/PND.log]
datetime_format = %Y-%m-%d %H:%M:%S
file = /opt/apache-tomcat-8.0.26/logs/PND.log
buffer_duration = 5000
log_stream_name = {instance_id}
initial_position = start_of_file
log_group_name = /opt/apache-tomcat-8.0.26/logs/PND.log
[/var/log/secure]
datetime_format = %Y-%m-%d %H:%M:%S
file = /var/log/secure
buffer_duration = 5000
log_stream_name = {instance_id}
initial_position = start_of_file
log_group_name = /var/log/secure
[/var/log/messages]
datetime_format = %b %d %H:%M:%S
file = /var/log/messages
buffer_duration = 5000
log_stream_name = {instance_id}
initial_position = start_of_file
log_group_name = /var/log/messages

Logs from /var/log/messages and /var/log/secure are making it to the AWS log console for CloudWatch but logs from /opt/apache-tomcat-8.0.26/logs/PND.log are not. My REST service is running on Tomcat.

When I ssh to the server I can see log entries streaming into /opt/apache-tomcat-8.0.26/logs/PND.log but nothing is showing up on AWS, however, from that same instance I can see all the log entries from messages and secure.

I checked out awslogs.log file and there are no "No file is found with given path" errors for "/opt/apache-tomcat-8.0.26/logs/PND.log" which makes me think it can find it. If I grep the file I get the following entries.

2015-10-14 16:33:12,585 - cwlogs.push.stream - INFO - 938 - Thread-1 - Starting reader for [xxxxxxxxxxx, /opt/apache-tomcat-8.0.26/logs/PND.log]

So if the file can be read, why aren't I seeing log entries?

I was wondering if perhaps, because the group existed before for another instance, if that somehow blocks the new entries for the new instance, but that doesn't make sense to me. Instances should be able to share groups, which is why we can view streams by instance id.
