Forked Repo keep using parent CI/CD variable instead forked variable

GitLab CI/CD

I am forking my repository which have CI/CD pipeline for building gitlab pages.
But whenever my forked project run the pipeline it keep using parent (main repo) variable settings, insteam forked variable settings.

I have tried running pipeline using https://gitlab.com/amalsholeh/crm/alhilal/-/pipelines/new, and define variable there, but it still using parent variable.

How do i force the building gitlab page on my forked repo to use its own variable settings not parent variable settings.

Below is my gitlab-ci.yml file config:

image: node

before_script:
  - npm install --force

cache:
  key: ${CI_COMMIT_REF_SLUG}
  paths:
    - node_modules/
    - .next/cache/

pages:
  script:
    - NEXT_PUBLIC_ENDPOINT=$API_ENDPOINT NEXT_PUBLIC_COOKIE_KEY=$COOKIE_KEY NEXT_PUBLIC_NAME=$APP_NAME NEXT_PUBLIC_COLOR_PRIMARY=$COLOR_PRIMARY NEXT_PUBLIC_LOGO=$LOGO_URL NEXT_PUBLIC_APPICON=$APP_ICON_URL npm run-script build && npm run-script export
    # - mv out public
    # - mkdir .public
    - cp -r out/* public
    # - mv .public public

  artifacts:
    paths:
      - public
  only:
    - main
