Uploading documents as PDF, but they download as something else after uploading

Hi all!

First time poster and applier here!

I'm not sure if this is supposed to happen, but when I redownload my uploaded documents from the JET application, they are not downloading as a PDFs. I am uploading them as PDFs and I'm just wondering if this is supposed to happen?

I just want to make sure my documents are accessible and I know that the application doesn't accept file types it's not supposed to, so please let me know if this is normal. 🙂

(I would attach and image to show what it looks like but I don't think I can? Here's a sorry description: Window's logo with a lock to the right and a black bar beneath the two symbols)

Thank you!!
