ERROR: Discrepancy between fastq files at record with first index

[NACasillas]

I'm getting this error: ERROR: Discrepancy between fastq files at record with first index @LH00269:168:22F35GLT4:6:1101:43250:1014:CNTAGATA+CNGGCTCT/1

I have dual index illumina paired end files that I want to demultiplex after they were unmatched in a bcl2fastq run, but I'm getting this error. The names look the same to me. Am I missing something?

I'm running this src/deML -o t1/demux -i idx.txt -f t_r1.fq.gz -r t_r2.fq.gz -if1 i1_r1.fq.gz -if2 i2_r1.fq.gz --mm 2

This is the first 20 lines of each file:
