Help with Issue " SQL that returns multiple rows is DEPRECATED"?

Anyone knows why the Linux machine at my GF's place would be getting the error below? The Win10 setup at my place doesn't get this error?

It doesn't seem to happen with the local library, more of an issue with Spotify... long pauses between song... hickups etc
