Update:
I seem to have over looked one thing concerning AO, as to why my site/webpages are passing the Google Mobile-Friendly test now.
Under "Cache Info," I unchecked the box "Save aggregated script/css as static files?"
When leaving that box checked, it caused the Mobile-Friendly test to fail each time. Unchecking it caused the test to pass each time. I ran the test today and it still passes the test.
