Copy Raster for a Raster Mosaic with Function produces corrupted data

[TonyDaSilva1]

I am trying to export a ArcGIS raster mosaic dataset to a new raster that has a "Elevation Void Fill" function on it to fill holes in the data, but I am finding the function data is getting corrupted when exporting to a new raster.

Any ideas on how to remedy this?
