new_est_reads between samples

Hello, when I was evaluating kraken2 results using bracken2, one of the samples was added_reads
That's orders of magnitude more. For example, there are 323 reads of g__Gabonibacter in kraken2, while 1249867 reads of braken2new_est_reads. There is only one species of g__Gabonibacter and 350 reads of new_est_reads. Other samples of g__Gabonibacter were evaluated in the hundreds.

s__Gabonibacter massiliensis is the only species of g__Gabonibacter. All samples are evaluated at the species level in the same order of 10^2. I do not understand why the evaluation at the genus level is so different
