Cannot save NLU pipeline in Rasa X frontend: Save button not visible in Chrome

[Deprecated] Rasa X Community Edition
1

I deployed Rasa X (version 0.21.6) using the Ansible playbook. When logged in with the interface and Chrome (version 79.0.3945.79) I can edit the NLU configuration but there is no option to save it. The only option is to leave the page and lose the changes.

Is this supported with a newer Rasa X version? If not, how can I override config.yml file in docker-compose?

Leaving the Configuration page screen capture

There is no “Save” button on the configuration page.

When logging in “production” and “worker” Docker containers, the config.yml file contains different settings compared to settings displayed in Rasa X frontend.

Configuration (not editable) displayed in Rasa X:

pipeline: supervised_embeddings
language: en
policies:
- name: MemoizationPolicy
- name: KerasPolicy
- name: MappingPolicy

Configuration found in deployed Docker containers:

# docker exec -ti rasa-production_1 bash

root@dcac7a78f4d8:/app# cat config.yml 
language: "en"

pipeline:
- name: "SpacyNLP"
- name: "SpacyTokenizer"
- name: "RegexFeaturizer"
- name: "SpacyFeaturizer"
- name: "CRFEntityExtractor"
- name: "EntitySynonymMapper"
- name: "SklearnIntentClassifier"
- name: "DucklingHTTPExtractor"
  url: "http://duckling:8000"

root@dcac7a78f4d8:/app# exit

# docker exec -ti rasa-worker_1 bash
root@9beec7f23b3c:/app# cat config.yml 
language: "en"

pipeline:
- name: "SpacyNLP"
- name: "SpacyTokenizer"
- name: "RegexFeaturizer"
- name: "SpacyFeaturizer"
- name: "CRFEntityExtractor"
- name: "EntitySynonymMapper"
- name: "SklearnIntentClassifier"
- name: "DucklingHTTPExtractor"
  url: "http://duckling:8000"

Update: The Save button is visible in Firefox but not Chrome. Even with the button, will the changes take effect since config.yml files found in Docker containers are not the same? Which file actually takes precedence?
