Editing Widget's new features are not showing there labels

Hello all,

I've made a application for assigning new addresses in my city using the ArcGIS Viewer for Flex - Application Builder it uses the editing widget to place the new address. The engineer I made it for mentioned that when he assigns a new address the label doesn't show up for it like the others. I went on and looked at it and saw that just a few other addresses are missing there label as well but just 3 or 4 and when I tried adding a address the label didn't show up.

Any ideas on what might be happening?

Thanks!

Chris
