metaphlan profile not showing any relative abundance

[DEEP CHANDA]

        I used prefetch tool of "SRA-TOOLKIT-2.9.6" was used to download SRR11048974 (.sra file). It was converted to .fastq file by fastq-dump of SRA-TOOLKIT. this .fastq file was analysed by "MetaPhlAn version 2.96.1 (02 Feb 2020)". But both the "SRR11048974.fastq.bowtie2out.txt" and profile "SRR11048974.txt" files are not giving expected result. ( I have attached relevent files after compressing it due to their large size; please extract to see). Facing same output for many other files also.

        But i found similar result when run the example samples given in tutorial link (https://bitbucket.org/biobakery/biobakery/wiki/metaphlan2#rst-header-run-a-single-sample).    

        I'm a newbie in this field. please help me in simple understandable language.

Thanks in advance.
