Cover Letter seems to not have been processed with my application

I just submitted an application through my city’s job posting for a library assistant - circulation services position. I’ve been hoping for this type of role to get posted for a while now, so I hopped on the chance.

One of the sections asked to upload my job resume and cover letter, which I uploaded them both. But somehow, when I’m reviewing the application, it only shows the resume uploaded. I can’t go back into the application because I submitted it and now I’m starting to freak out.

I feel like I botched my chances. My cover letter felt like a strong element to the application and now they won’t even see it. I’m upset. Is there anything I should do?
