Parsing settings for YAML file plugin

I am trying to parse the value language strings in source and target columns in the Editor in the snippet of YML code below.

---
permanent_link: adult_consent
linked_steps:
- step_index: 0
  content:
    translations:
    - locale: en
      field: title
      value: Before We Begin
    - locale: es
      field: title
      value: Before We Begin

When I use the Extract button on the file, I get the following for the Source path expression

linked_steps\[\d+\]\.content\.translations\[\d+\]\.value 

When I import the file into Trados, both values are in the source column in the Editor.

How should I write this for a bilingual file in the Source Path Expression and the Target Path Expression?
