Session and Startup do not show suggestions for applications

If I didn't post it to the proper package can you please move it to where it belongs? Thanks.

Basically in Session and Startup - Application Autostart, if I click the + sign to add a new application it does not show any suggestions while typing in the Name box:

However when creating a new launcher and such, same dialogue window, will showcase suggestions based on the installed apps on my system. And it is very very useful.
