DSP effect "Bit Depth" causes loud distorted audio when converting 32bit float

System: Windows 10
Version: 17.6 64bit

When converting certain 32bit float .wav file, DSP effect "Bit Depth" causes distorted audio, in all encoding format (.flac, .mp3 etc.)

Using format option has no problem

The problematic .wav is generated by Bitwig Studio
encoder setting shows IEEE float
but sample size is 32bit
Perhaps the DSP effect is unable to identify the 32bit file as float
