External Payment - There is no record type 2_DETAIL in the file

Hello, I’ve found similar topics to this problem, but the resolutions are not working for me. 

We are trying to upload a file of customer payments to a Mixed Payment and have it match to customers.

I’m using the File Type ExtCustPayment. After uploading, I receive the message: There is no record type 2_DETAIL in the file

Test file:

Any help would be appreciated. Let me know if there is something else you need to see.
