All documents are not attaching to emails

Two documents were attached to the Jotform however only one of the documents got attached to the email when it was sent??

I cloned and tested your form. It seems everything works as expected. Following images shows the results of my test submission.

I also sent you a test submission to see if anything goes wrong. So there is nothing wrong with test submission as you can see below.I hope it helps. If you have another issue, please feel free to contact us.
