Transform Entity ID to Label missing

Problem/Motivation

Created a new facet using Search API and Views, when configuring the facet the option for Transform Entity ID to Label is missing. Option appears on other facets created using the same index and functions as desired, but does not appear for this specific facet.

Steps to reproduce

Create Search API index with relevant fields
Create View with content from that index
Create facet for the view, when configuring, desired option is missing.
