Manual submissions not showing up

Hey fellas,

I'm new here and just submitted about 5 new manuals to the database on Thursday, but they haven't shown up. For each, I got through the upload, then a page loaded which listed all the pages' names and said "processing" as well as "Checking for missing pages". This screen never advanced on its own, so I figured I was done for each.

Is that what submission normally looks like? Did I do something wrong? I have a lot more manuals to submit, so I want to make sure I'm doing it right.

Also, for clarity, I'm using PNGs that are zipped.
