Activities Section Hrs/Wk Typo

For my activities section in the Common App, with my top activity which is something I run through my school, instead of 40hrs/wk, I posted 4hrs/wk… I wrote about it in my essays and I have a leadership position through a publication I run. I applied to more exclusive schools, so I don’t know what I should do about this. Does this merit correction and do I need to worry?

I apologies for the wrong title in the chat, I mean a Wks/Year Typo.
