DJUCED recording file format

Hi, I have an issue with DJUCED recording. When i started recording one month ago, the output (save without compression) was a XTML5 file (that was ok). I should have changed something on djuced settings and now it converts every mix in WAV format (that creates files of more than a GB even with the lowest quality set, that is too much for me since I cannot it convert it to mp3 with common converters online). I tried to set the default settings, but I still have the same issue. What has happened? Do you have any suggestion on how to turn the file output back to XTML5 or another lighter format?

Thank youu
