Warn: Multiple node fields resolve to the same GraphQL field

I am getting the warning messages when run gatsby develop. It's still being run but I can't figure out what causes the error message

Below are the example warning messages
warn Multiple node fields resolve to the same GraphQL field Airtable.data.Project - [Project, Project___NODE]. Gatsby will use Project___NODE.
warn Multiple node fields resolve to the same GraphQL field Airtable.data.Publication - [Publication, Publication___NODE]. Gatsby will use Publication___NODE.

The version library in package.json
"gatsby-source-airtable": "^2.0.8",
"gatsby": "^2.18.13",

Does anyone found a solution yet?

Many thanks
