I can not upload the following documents on my application. It will not let me save or submit my application. Please advise. This is my fourth post about this and no one is helping.

Hello,

I tested the form and I was not able to replicate the issue. Could you please share more information on what you're trying to do when that error message appears?

Here's my submission test:

I was able to click the Next button and I was able to save the form without any issue. Please check if my test submission is correct. If not, please let us know how to replicate the issue.
