The optimiser limits its range of Q/bandwidth adjustment so that filters do not get narrower than 3Hz bandwidth or broader than 15Hz and Q does not get lower than 3.0. This is because it is targeting room resonances, which occupy that range of bandwidths. For broader or narrower filters make manual adjustments.
