Cannot Hide Mosaic Dataset Footprints in Map Service

[KeonMonroe]

I have a question similar to this post but it was marked as resolved so I am posting again. 

I need to publish a cached map service from a mosaic dataset using ArcGIS Image Server without any footprints showing. Once published the Footprints of the mosaic dataset are visible - which is distracting because the its intended use is for custom basemap imagery. 

I have tried hiding the Footprints + Boundary in the table of contents in Pro, and I made the outline colors for them transparent. So in Pro only the imagery is visible - but once published the service will include Footprints (visible as lime green outlines). This behavior does not occur if I publish as an image service, but that is not desired for performance reasons - I would prefer a map service. 

Any suggestions on how I can fix this?

SOLVED By Deleting the cache item and republishing it as a new service (with the mosaic dataset's footprints disabled in the table of contents). 

This is happening because I originally published it with them on, then chose to overwrite the service with the Footprints off. I should have stopped and deleted the original instead because for some reason the visibility setting isn't updated when overwriting (or the setting is somehow not acknowledged).
