Error (List index out of range) when training custom model and crop mode is first - 5th WEC

[GrunCrow]

When I try to train a custom model with my own data, divided in different folders with the species mode I receive an error: "List Index out of range". I chose default settings but the crop mode which I've set t first. Log file seems to be corrupted.

If I try it with the crop mode set to Center it works.

I will attach the log file and dataset later so you can reproduce the error.
