Build hosted Tile Cache

[PLadd]

I have a hosted Tile Layer that I am trying to build cache for. 

• I did the first three levels fine (and have done all levels on other hosted layers without issue). 
• I keep trying to build the 1:6000 scale but nothing happens. 
• I wait (a long, long time) and still nothing. 
• I check the status in ArcGIS Server hoping it would say something like "In progress" (like Job Status in APro).  But it looks the same as below.

I think the issue is the discrepancy between "Visible Range" and "Tile details" in the image below.  It seems like if "Tile range" would reflect "Visible Range" the cache would start building.  I've tried tweaking and saving "Visible Range" hoping it would jar the "Tile Range" into action.

Any guidance is appreciated.

Update (but still no fix).  Because my scales are set to specific scales, instead of just using the little slider tool, which sets scales different from mine, I was able to manually input my "Visible Range" to match my Tile Range details.  Sadly, this didn't affect any change to the Tile Range slider.

I also went to ArcGIS Server manager and stopped/started SceneCachingTools, to no avail.  Lastly, I tried in APro to use "Manage Map Server Cache Tiles" GP.  It ran and said it was happy but no cache was built for the 1:6000 scale.
