Hi Noah,
There are a number or settings at play which is causing this issue for you.
The first of which is that you do not sound likle you have interconnects as accessories to the products that use interconnects.
The second is that it sounds as though you are building your project through the drawing process and not building your project in text to ensure completeness and then creating the drawings.
This link goes to a newsletter article we did that explains how to configure your database for custom length interconnects.

You can surely glean some knowledge from it, however the methodology is highly dependant on using D-Tools as described above, as well as bringing all your rough-in wire into a project through PACKAGES where wire length is set in the package, leaving you the option to set a very low default wire length in you project settings for that is appropriate for interconnects.
If you do nothing to address these compound issues, the short route is to just go to 'D-Tools>Options' in your project and set the default wire length in the project to something like '3' and leave that setting while you are generating you schematics.
