In this scenarios, Documentation is key :
Modifier
Usage
set
Set or replace the field value(s) with the specified value(s), or *remove
the values if 'null' or empty list is specified as the new value.*
May be specified as a single value, or as a list for multivalued fields
add
Adds the specified values to a multivalued field.
May be specified as a single value, or as a list.
remove
Removes (all occurrences of) the specified values from a multivalued field.
May be specified as a single value, or as a list.
removeregex
Removes all occurrences of the specified regex from a multiValued field.
May be specified as a single value, or as a list.
inc
Increments a numeric value by a specific amount.
Must be specified as a single numeric value.
In my opinion "set" is the right direction to look into.
Not sure what happens if you use the remove to remove only a single valued
field value.
Can you explain us what you noticed ? An empty value remain for that field ?
It is kind of weird, I would expect the field to become null.
