Cause

Section titled “Cause”

The issue reported that, when editing a provider, a generic configuration fragment was merged into the form before extraction from the already-overwritten content, preventing custom values from being extracted. The maintainer replied that 4.0 removed generic configuration fragments. When switching providers, it replaces only key fields such as the address, key, and model, while preserving other content in settings.json unchanged. Therefore, this timing issue does not occur in 4.0.

A later comment reported a separate, earlier-stage case: the stored configuration may overwrite settings.json on disk before extraction. The comment did not confirm that the 4.0 explanation resolves this case.
