How do you suggest that KoLmafia discover that something has sold? You don't get an event. It would have to continually parse the store log and notice new sales as they come in.
Aside from the fact that this is not a "Bug" by any stretch of the imagination - sales from your Store have nothing to do with your "Session Results" (the results from your "Session" - things that YOU did, rather than things that passively happen to you, like selling stuff in your store or people sending you meat or items in kmail) - I don't see any reasonable way to do what you want.
Rejected.
