Numbers document created on web not showing up on phone

If I create a Numbers spreadsheet using the iCloud Numbers web interface, it does not show up on my phone. I can create a spreadsheet on my phone, and it shows up in the web interface right next to the sheets created on the web. I can modify/delete the sheets I created on my phone from the web interface, and it updates immediately on my phone, so I can see that syncing is working and I'm looking in the correct location/folder.
