Different results with LEfSe in Galaxy

Hi everyone,
I’m really confused because I generated results with lefse on galaxy on February 7, 2023. I forgot to retrieve the LDA scoreboards. I’m back today with the same input .txt file and the LDA scores are no longer the same! Why not? What updates have been made? I don’t get it at all! can someone explain why I get different results with the exact same input file?

Thank you so much
