Limiting decimal places in labels

Original LIDAR ground elevation measurements go to about the 20th decimal, but I only need the labels rounded to one decimal point.

 

Using the following label expression, it rounded about 25% of the 2-million labels, but the remaining are still showing all 20 or so decimal places. (see attached image)

 

$feature.NGVD; round(number([$feature.NGVD]), 1)

 

The field name is "NGVD."

 

I'm purplexed as to why it appropirately rounds some but not all the labels.  They're all in the same data field.
