Unexpected behavior when downloading fastq using SRA identifier

I ran kingfisher and it pulled 3 fastq files for 1 record. A single ended and 2 paired end files.

(base) [jespinoz@exp-15-28 split_reads]$ kingfisher --version
0.3.1

ID=SRR13615821
kingfisher get -r ${ID} -m aws-http -f fastq.gz

I thought that maybe one was interleaved but the read sizes didn't match up:

(base) [jespinoz@exp-15-28 Fastq]$ seqkit stats SRR13615821_1.fastq.gz SRR13615821_2.fastq.gz split_reads/SRR13615821.fastq.gz

The above files were what were downloaded by kingfisher.

Note: I moved SRR13615821.fastq.gz into a separate folder to split the reads but BBSuite said there were no pairs:

The above is me trying to split the reads manually.

Do you know what could be happening?
