[Bug]: UI remains readonly in dev-env and configurations in yml have no effect

[MLindenhofer]

Expected behavior

In dev-env the Save Button should be not read-only and changes in yaml should not be ignored.

Actual behavior

I can't apply changes on my configurations anymore. The UI Save button remains in read-only state even in dev environment. So I tried to do the changes I needed to do via the yaml-file, but even after running the cache-clear & rebuild workspace and rebuild definitions command my changes did not appear in the admin backend. Every change in my ShopData.yaml in /var/config/data_hub/ is ignored.

Steps to reproduce

pimcore 11.1.6
datahub version 1.7.4

I also have this setting in my root config/packages/dev/pimcore_data_hub.yaml:

pimcore_data_hub:
    config_location:
        data_hub:
            write_target:
                type: 'symfony-config'
                options:
                    directory: '/Volumes/projects/myproject/var/config/data_hub/'

ShopData.yaml (sample)

pimcore_data_hub:
    configurations:
        ShopData:

                                    isOperator: false

The only thing I noticed too is that the same behavior is in the "System Settings".

Has somebody of you experienced similar problems?

Thanks in advance
