Tengo este problema al cargar un archivo csv en IXP

Datasets with this source added will contain any successfully uploaded messages.

Re-uploading messages with the same text and IDs will not consume additional AI units for messages that were already uploaded successfully.

Me manda este error sin embargo no archivo no cuenta con ese numero de filas, ya intente subir el archivo de 500 registros 1000 registros pero sigue sin solucionarse alguna idea?
