DRC-FIR will not convert .wav file from Room EQ

Fusiondsp with volumio on RPI4

I have created peq L and R filters in Room EQ and works fine in Fusiondsp

When I create impullse response and then export as .wav either as separate files or a stereo file I have probems. I place the file in filter-sources and try to create filter. Fusiondsp reports error - image attached. Previously there was another error that doesnt stayy visible long something about couldnt acess file or folder, not seeing that error for a while.

Here is error:

SOX failled to convert filleError
Command failed /usr/bin/sox/data/INTERNAL/FusionDsp/filter-sources/LR inv response-Mar26-44k.wav -t f32 /tmp/tempofilter.pcm rate -v -s 44100 /usr/bin/sox/ FAIL
