Expected Behavior vs Actual Behavior

I want to synchronize my songs using the sync option, while updating the m3u file using --m3u FILE.

My songs are playlist-based, so i use --output "{list-name}/{title} - {artists}.{output-ext}" to classify them

I can create the initial synchronization and generate the m3u, but cant resume the sync while using the --m3u FILE.m3u option

spotdl --m3u FILE.m3u sync FILE.spotdl works spotdl --output "{list-name}/{title} - {artists}.{output-ext}" sync FILE.spotdl works spotdl --m3u FILE.m3u --output "{title} - {artists}.{output-ext}" sync FILE.spotdl works

But when using m3u option alongside custom output with {list-name}, it doesn't spotdl --m3u FILE.m3u --output "{list-name}/{title} - {artists}.{output-ext}" sync FILE.spotdl gives the error on traceback

Steps to reproduce - Ensure to include actual links!

Create a synchronization file Try to sync with an existing sync file using the --m3u FILE.m3u option and --output FORMAT, while FORMAT having {list-name} somewhere in it
