TypeError: train() got an unexpected keyword argument 'focal_loss'

Hello and thanks in advance for any help!
I have installed the latest version of BirdNET-Analyser (08/05/2025) and I am just trying to execute a simple standard training command as shown in the documentation with the recommended dataset for checking the installation, but I keep getting this error at the very beginning of the script launch:

Traceback (most recent call last):
File "", line 198, in _run_module_as_main
File "", line 88, in _run_code
File "/home/eric/BirdNET/BirdNET-Analyzer/birdnet_analyzer/train/main.py", line 3, in
main()
File "/home/eric/BirdNET/BirdNET-Analyzer/birdnet_analyzer/utils.py", line 27, in wrapper
return f(*args, **kwargs)
^^^^^^^^^^^^^^^^^^
File "/home/eric/BirdNET/BirdNET-Analyzer/birdnet_analyzer/train/cli.py", line 13, in main
train(**vars(args))
TypeError: train() got an unexpected keyword argument 'focal_loss'

Thanks very much for any help!
