Unwanted Small (~80bp) Bioanalyzer Peaks

[Daytwa]

After PCR enriching some libraries I noticed small peaks of 80 bp in all of my samples (see image). I am using NEB's ChIP-seq kit for Illumina. My inserts are ~65 bp. I see this in my negative control too.

Reading around on the forum it seems that these are likely unreacted/excess primer. I would size select but I'm worried about sample loss since my peak is so small. Do I need to worry about them hybridizing to the flowcell?

If anyone has some insight I'd much appreciate it. Thanks.
