You will need to remove the "saved object" in Kibana. To find the document run the following query in the Console under Dev Tools
GET .kibana*/_search
{
"query": {
"match": {
"_id": "infrastructure-ui-source:default"
}
}
}
That should return one result which you can either update the document to remove that setting OR you can just delete it and try again. If you choose to delete that document that would look something like this:
DELETE .kibana_1/_doc/infrastructure-ui-source:default
The only thing you might have to change is the .kibana_1
index to match the index returned in the document (from the previous query).
