Class rank weighted vs non-weighted

So I have already applied to a few colleges through common app, and there was this section that I needed to list my class rank… and then select weather it’s weighted or non-weighted … i think i accidentally selected weighted, and my rank was 1 (according to my transcript) if this was a mistake, then will this affect my college admission??

Does your school use weighted GPA? I think you should figure out whether or not you actually made a mistake before worrying about one.
