Inconsistent output formatting

[spitfiredd]

I am getting an output text file with inconsistent formatting, here is a snippet of some of the output I am getting.

Take the following snippet of text output,

NODE_2_length_14983_cov_10.199960_8	K01424
NODE_2_length_14983_cov_10.199960_9
NODE_2_length_14983_cov_10.199960_10	K02055

Running expand test.txt -t 1 > test.txt cleans up all my output files,

For reference I am using version kofamscan=1.3.0 and my script is,

  exec_annotation \
    --cpu $task.cpus \
    -k $ko_list \
    -p $profiles \
    -f mapper \
    -o ${sample}.kofam.txt \
    ${faa}
