It looks like only 90 of the images you intended to upload were successfully uploaded. The Overlap Report shows that all of them were included in the output and the details show only 90 were uploaded. This can happen if you have a lot of failures but there are no gaps in the 90 images so that doesn't sound like it was the issue.
We will provide a refund since it is technically just a free job with your Pro tier subscription. Please be careful to make sure your uploads are successful.
