Hi all, I have a question.

I have performed a 16S rRNA analysis using the following pre-trained Silva database and obtained the following annotation results.

(Downloaded database) Silva 138 99% OTUs full-length sequences

(Obtained weird taxon) d__Bacteria; p__Bacteroidota; c__Bacteroidia; o__Bacteroidales; f__Muribaculaceae; g__Muribaculaceae; s__uncultured_bacterium

Why are the names same for family (f__Muribaculaceae) and genus (g__Muribaculaceae)? I don't know if there is something wrong with the database in the first place or if it is some kind of manipulation error on my part.

I would appreciate any advice anyone can give me.
