I am trying to create some helpers using GUI. However, some entity types are unavailable for creation. I suspect that all those unavailable are the ones where I have previously created helpers in yaml.
There was not much that cannot easily be recreated in GUI so I wanted to move everything to a single yaml-free interface. What I have done so far is:
Deleted the helpers in the GUI
Deleted all references to yaml-helpers from configuration.yaml
Deleted all input_* files from the .storage folder
Checked the core.entity_registry-file
Finally sought through the entire config-directory; no traces of input_* anywhere anymore.
The only thing I can think of now is some kind of setting stating that a manual helper-entry exists for those particular types which disables creation through the GUI.
Does anyone have a clue?
