Please informed that you need to add once again the LPCO doc type 893 as per AIRS recommendation.

Please note that the 893 is a dematerialized so Image not required.

For License number must be 8 digit alpha numeric. Based on the provided docs (for example) the license number is 4RPNGCLY instead of 1234SFCL.
