The Spitter spawner info says it contributes biters.

And it does.

Oh, nevermind then.

The wiki has a calculator for spawn chances depending on evolution factor. It seems that spitter spawners will only start spawning spitters when the evolution factor is >0.25, which is a tad more than the 0.23 shown in your picture. Biters will still be spawned as long as evolution is <0.35.
