Help- "Host Runtime Files" setting re-sets upon publishing

Having a strange situation, here...

I am trying to publish an Edge animation, in a mode that I call "Vanilla."  This means that all the checkboxes on the right-hand size of the publish setting window are UNCHECKED.  Specifically, the "Host Runtime files on Adobe CDN" box needs to be unchecked.

My procedure:

1: Go into export settings

2: Uncheck that box

3: Click "save" in settings.

4: Save file

5: Publish animation.

I open that published file, and- whaddya know- the "Host Runtime files on Adobe CDN" box is checked, again!

Upon publication, edge seems to be overwriting my publish settings.  How do I turn this "feature" off?

Thanks for any help you can provide!!!
