P_PHILC is a MIDI style. The probable cause of the bass drops is the bass patch isn't playing in the proper octave making some notes be out of the range of the patch.

This can be corrected with editing in the Piano Roll screen or alternately change the Bass to a MST instrument or RealTrack Bass.

I created a song test file and the Style changes between A and B styles worked correctly in the test song. Save your song project, close and reopen the project and regenerate may correct the issue on your system.
