Gitlab CI problem with merge request and multiple modules on JAVA project

Question

I've problem with Gitlab CI pipeline if I commit and push like below. My pipeline run build, test exactly that module what I modified, but after merge pipeline runs package and deploy all modules, even these modules which have nothing new in repository.

in root module.gitlab-ci.yml

.root-module:
  variables:
    MODULE: "root"
  only:
    changes:
      - "root/**/*"

in abreg module.gitlab-ci.yml

.abreg-module:
  variables:
    MODULE: "abreg"
  only:
    changes:
      - "abreg/**/*"

How can I modify my.gitlab-ci.yml file to achive pipeline which run only these modules which I surerly changed?
