Not an issue as I use the inner almost exclusively for climbing and therefore not with the smaller cassette sprockets.
I have the same issue with my climbing bike when on the middle of a triple crankset.
It is a road frame with a 10s XT drivetrain.
It took me a while to figure what was causing that noise.
