Tool name: MetaPhlAn v4.0.6

I want to establish the relationship between reads and abundance, so I used the hyperparameter --bowtie2out metagenome.bowtie2.bz2 to save the Bowtie2 results. Each line is an ID and UniRef90\_R5B287|1\_\_8|SGB2091. I assume SGB2091 corresponds to the species of the reads. However, after manually calculating, I found that it does not match the output of MetaPhlAn’s profiled\_metagenome.txt. The main reason is that there are many elements of SGB group such as SGB\_14546\_group in the abundance result but not in Bowtie2 results.  
I would greatly appreciate any suggestions you may have. How is the SGB group constructed?
