Bug in both Music Converter and Batch Converter

[Test223311]

Hi,
Today I tried this app, trying to see how is working. I tested only on 1 flac and I found this bug:
I tried to convert a flac file to mp3 320 CBR (with mp3 lame, settings "-b 320 -q 0 --noreplaygain"), the resulted mp3 file is showing in Mediainfo this:

Audio
Format                                   : MPEG Audio

Format profile                           : Layer 3
Format settings                          : Joint stereo

Sampling rate                            : 44.1 kHz
Frame rate                               : 38.281 FPS (1152 SPF)
Compression mode                         : Lossy
Stream size                              : 8.34 MiB (99%)
Writing library                          : LAME3.100
Encoding settings                        : [COLOR="*FF0000"]-m j -V 4 -q 0 -lowpass 20.5[/COLOR]

What is this? Anyone can reproduce this bug. So the bit rate is CBR 320 kb/s, "achieved" with those encoding VBR settings? Tried to see where it may bring, of course encoding with the displayed VBR settings creates a 256 kb/s mp3, smaller in size anyway.

Is this known bug or is only me?

Thanks

No where in our program do we have lowpass:

Encoding settings : [COLOR="*FF0000"]-m j -V 4 -q 0 -lowpass 20.5[/COLOR]

Also if you hold the mouse over the file, dBpoweramp will show the encoder settings
