I'm having the same issue uploading documents for my interview. I went in recently and found that all of my documents have been uploaded twice. When I go to delete 1 it deletes both copies. I tried to save and just try again uploading everything once but I am getting an error code. I think there is something wrong with the attachment section of the application. I have heard of other people having issues, luckily this is my first issue with the new system. I plan on explaining it to the recruiter during my zoom interview.
