Extensible Flexfield (EFF) returning null in Business Rules for Position Redwood Page

Summary:

Hello,
On the Position page in Redwood, I am trying to set the value of a field based on another field that is configured in an Extensible Flexfield (EFF).
In the Responsive UI, this was implemented through an Autocomplete rule. However, since Autocomplete is not supported in Redwood, I am migrating the logic to Business Rules.

Expected Logic:
If the Location is not null, retrieve the value from a field in the Location EFF (Additional Info) and populate it into the Centro de Responsabilidade (DFF).

Issue:
When I select a Location, Centro de Responsabilidade field is not being populated.
