I create pipeline with interface choose in dropdown list of some values for our developers

variables: &global-vars
  TECH_USER_DEFAULT: "default_tech_user"
  TECH_USER:
    value: "default_tech_user"
    options:
      - 'tech_user_etl'
      - 'tech_user_cicd'
      - 'tech_user_migration'
    description: "${TECH_USER_DEFAULT}"

In WEBUI on place with description view ${TECH_USER_DEFAULT}

Try else variant over workflow and rules

workflow:
  rules:
    - if: $CI_PROJECT_URL =~ /system1/services/
      variables: &global-vars
        TECH_USER_DEFAULT: "default_tech_user"

Got same result.

How solve with problem?
