Problem on FIR filter in sigma studio

I tried to use FIR Filter Block(coefficients calculated by MATLAB) in ADAU1701 and ADAU1452. But I get different results. ADAU1452 provides a linear phase FIR filter, but I don't want it. 

I guess FIRSigma300Alg and FIRFiltAlg are quite different. FIRSigma300Alg has an unknown treatment on phase response.

So how can I use FIR Filter Block like ADAU1701(FIRFiltAlg) in ADAU1452 board? I want a clear FIR filter with no other treatment in ADAU1452 board.

Thank you.
