I have created a mosaic dataset (in FGDB) for some orthophotos and set the Source Type for that mosaic dataset to "Processed". I've then created a tile cache from that. The tile cache did not "inherit" the Source Type, but instead says "Generic". I've tried to "Switch to" the "Processed" Source Type via Catalog, Properties (see attached screen shot), but when I hit "Apply" the Source Type reverts to Generic. How do I set the Source Type to Processed for the tile cache (and does it matter)?
