Vector project with polygons visible from 5 to 5 and labels from 5 to 16 produces incorrect result

[tst-blaird]

I created a vector project to draw polygons with labels. The polygon visibility was set to "5 through 5". The label visibility was set to "5 through 16". I created a 3D globe using this vector project and blue marble imagery with a small amount of high resolution imagery in the area of the polygons.

The result of viewing this globe in the Earth Client is that the polygons and labels show up at zoom level 5 and then both disappear at 6. The labels are not visible to level 16 as they should be.

I created a portable file from this globe and found the following:

• Vector packets only existed at level 5.
• There was only one zoom range proto struct in the dbroot nested feature with a min zoom level of 5 and a max zoom level of 6.

Expected behavior

The polygons and labels should have been visible at zoom level 5 and then only labels from zoom levels 6 to 16.

If my understanding of the packet structure is correct, I would have expected landmark and polygon packets in the portable file at level 5 and then only landmark packets at level 6. It would have expected two zoom range proto structs: the first with min/max of 5/6, and the second with min/max of 6/17.

Additional context

Note that I also tried a similar vector project with polygons visible from 11 to 13 and labels from 8 to 16. The globe and portable file using this vector project worked as expected.
