The errors that you are seeing are API warnings and error codes produced from constituents who have paid using Paypal. The maximum field length for the Error Code column in your Luminate transaction report is 255, which is why the error appears to be cut-off at the end. The part of these errors that you want to pay special attention to is the number that comes after "ERRORCODE0=" which can then be cross referenced with the Paypal API Error and Warning Codes list.
