I want to encode my FLAC files to mp3. I've set it up like this:
- Re-encode Lossy As: mp3 (Lame)
- Mode: Variable Bit Rate (VBR)

Right column: Copy 1:1 Audio Tracks Which Are: mp3 (only)

File Naming: Sub Path\Source Filename


Under 'Audio Types' I only have FLAC and mp3 checked.

This results in zero (lossy) tracks being encoded. The log says this:

Code:
Sync started on Monday, 26 August 2019, 11:03:41 to foobar2000 on Xiaomi Mi 9 SE
Sync incomplete.
 2 tracks, 2 tracks requiring syncing

  Storing /_H/Hellfish - Black Death/Hellfish - Black Death - 01 Doctor Beak.mp3
  Unable to store /_H/Hellfish - Black Death/Hellfish - Black Death - 01 Doctor Beak.mp3

Any idea what could be going wrong here?

Thanks in advance
