STM32F4 FFT problem

I have installed all DSP source files on the project and f32 fft works perfectly, but when I switch to q31 or q15, while  the input buffer shows got data, the output buffers all values (the frequency spectrum) are 0. All the files were replaced to the same files for q15 or q31. Has anyone encountered this?
