using LEfse on the galaxy

Hello everyone.
It’s my first time that I want to use galaxy specifically LEfse.
I have read the tutorial and it seems its easy to use but I think there is a problem which I don’t know what is it.
I exported my data from qiime2 and make in a form of relative abundance and “biom with taxonomy.tsv” and then kept just genus level. if any row didn’t have genus level I used the higher taxa level but with () around the name.
but when I use LEfse the result doesn’t make sense. could you please let me know why?
I send you my data and the result picture.


Thank you
