A library within a library (.lvlib linking issue)

[Gregory]

Hi all, I am having trouble when making copies of my library. For example, I have a user events library that I want to copy to send different kinds of user event data. I want the following structure (on disk and in the .lvproj):

Level1.lvlib

    User Event 1.lvlib

    User Event 2.lvlib

However, if I save a copy of User Event 1.lvlib to create User Event 2.lvlib, I get broken run arrows. It says it cannot find one of the library VIs, which is in fact right next to it on disk.

This only happens if I try to put the new library into Level1.lvlib. If both libraries are just under the LabVIEW project, I can make copies all day. Here is a little snippet of exactly what I am doing:

I'd like to get this working so I don't have to create the new library at the top level, and then drag and drop it to its desired location. I am using LV 2016 32-bit and my example project is attached.
