Why does packaging use an old lightmass solution?

I compiled a new lightmass solution which worked successfully. I received no errors, and I can play it on my computer. However, when I attempt to package it in Windows 64bit, it uses an older lightmass solution from several days ago. I do not understand why. I have saved this architectural model incrementally each day. I am currently working on level 6 of this project. I think the light solution is from level 3 or 4. I have tried to disable all other levels than level 6, but I just received an error when packaging.

Any ideas? Thanks for your help in advance,
