Solidworks electrical routing not auto generating wire lengths back in electrical

I have followed many tutorials about how to route electrical harnesses on SW 3D and have created the routes and flattened them with annotations and lengths in the BOM tables. I have also exported these to a drawing in SWE which is very nice. The one very important thing that doesn't seem to work is the lengths being updated in the report in SWE. Most of the tutorials showed this just magically happening once they returned to SWE from 3D. Mine, however, doesn't seem to have updated at all.

Also, I am routing only wires between two connectors, with no cables. I clicked "route harnesses", rather than any of the others in SWE 3D.
