I just realized the ansible output I put in my original post was incorrect.  I re-ran it just now.  Here is the correct output which is still having the same issue of running successfully, but the change is not seen in the management portal.
Output:

Content of all_disable_application.mergefile:

[Actions]

In the portal there was no change.

I had the same issue happen when using the Ansible expect module.
