If there is no UPC or ISRC reported from a partner, we have to go by the label / account / artist name. Thus, those royalties will land in a section called "Unmatched". We don't automatically do this for everyone but can provide assistance if necessary if you create a ticket but essentially, the answer to this is, if we don't have the information provided by a partner, we can't match it to anything within your queue of releases and thus, it has to land somewhere.
Your actual payment is not affected by this at all. This is strictly for you to utilize the "Sales Summary" side of our platform.
