Abnormal fastq lines

Hello all,
I obtained this SRA files from ncbi. Something appears to be off with the third lines and I am not sure what but its causing bowtie to throw the following error: How can I fix this?

Bowtie error:

What's visible looks fine. ASCII 10 is a line feed. You might need too investigate how to examine and remove white spaces from files.
