defined operator.valuesLabels not visible

[ctrlaltdylan]

Describe the bug
When creating a custom operator, the valueLabels don't show even when they're defined. See the geoproximity operator in this codesandbox:

https://codesandbox.io/s/nice-sunset-7n6c3?file=/src/config.js

To Reproduce
The codesandbox tells the story, for some reason the valueLabels aren't showing as options.

Expected behavior
I expect the list of valueLabels to display when the field is chosen and you select the next operator.

Actual behavior:

Additional context
This is a custom operator using a custom type in conjunction with a couple other custom operators.

Starting to understand the issue. I assumed that the 2 fields were supplied by the operator.geoproximity.valuesList property, but actually it's other fields with the same type - a.k.a. the geo type.

This presents a weird problem, the geo field only makes sense when comparing with another geo field with a modifier like number of miles/kilometers away.

I'll keep playing, but I didn't realize that the proximity comparison fields were not based on valuesList.
