I’m guessing those songs have RealDrums and the rest of the tracks are MIDI, since RealTracks did not exist before the end of 2008.

BIAB has a setting to replace MIDI drums if a more suitable RealDrum exists.

There is a place, I think in Options, Preferences, Audio where you can adjust the latency of a software MIDI synth with respect to the audio. This is a test song that you adjust until things sound together.
