Ugh. Didn't think about that it would mess up your reply rate. Definitely unfair to the seller. HOPEFULLY OfferUp will fix that, but I wouldn't hold my breath. (OfferUp itself seems to waste my time just like "no shows" do, such as me taking the time to report prohibited items but yet the listing isn't taken down, so I'm not optimistic they even care about fixing these sorts of things.) Good luck though!
