Cutadapt filtering 0bp

I got this after running cutadapt to trim adapters, but the report says 0 bp were filtered. Why could this be happening?

Total read pairs processed:        309,147,525
  Read 1 with adapter:                 573,790 (0.2%)
  Read 2 with adapter:             302,963,879 (98.0%)

== Read fate breakdown ==
Pairs that were too short:             708,546 (0.2%)
Pairs that were too long:          308,438,979 (99.8%)
Pairs written (passing filters):             0 (0.0%)

Total basepairs processed: 57,184,734,130 bp
  Read 1: 10,812,785,560 bp
  Read 2: 46,371,948,570 bp
Total written (filtered):              0 bp (0.0%)
  Read 1:             0 bp
  Read 2:             0 bp

Hi @biostaring,
I think that the report indicates that no reads have passed the filter (all of them have been filtered).

Regards
