Breton and Welsh in the Kernowek language, help
Thank you for the screenshots. I checked a few of the marked translations and can confirm, that these are shown due to the language fallback chain.
I opened https://phabricator.wikimedia.org/T256097 to allow a wider discussion and preparation of a patch.
No problem, I sent a patch to remove it.
They were already configured as fallback for Cornish on translatewiki, and I was just cleaning up configuration by moving some common things from translatewiki configuration to core configuration. I removed it from both now. It will take a few days until it's fully deployed on the Cornish Wikipedia.
