fix: Property filter duplicates property name in suggestion when the label is empty

[connorlanigan]

Description

When the label of a suggested value in the property filter is empty, it uses the value instead. However, the value contains the property name, so the property name is duplicated. With this change, an empty value of an option is correctly displayed as empty.
