These errors are being caused due to the source code of the transaction not finding an effort segment in LCRM with a matching source code. This behavior is controlled by Direct Response. This error doesn't mean the donation can't sync, it just means it can't add the donation to the expected Effort Segment in LCRM.

Some organizations use a custom field to hold the effort code info instead of the standard Source Code field to avoid the issue of random URLs trying to sync to the effort segments. This type of setup would require a billable engagement, contact your account manager if you're interested in pursuing this. If these donations do not need to go to a specific effort segment, then you can just delete the QPM errors.
