Smart Nav Links created via Load Level Instance are broken, but Simple Nav Links are fine

Maps brought in via Load Level Instance that contain Nav Link Proxys configured to use the Smart Link instead of the Simple Link end up creating a link at the center of the world instead of their actual location. For long and detailed version of the repro steps please reference the linked post.

This was reported and tested in 4.21.2 (CL-4753647). This was reproduced in 4.22.1 (CL-6063286)

1. Download and open the attached project
2. From MainMap press Play
3. Notice the navlink position on the loaded map
4. Exit PIE, open the Level Blueprint, and change TestMap1 to TestMap2 in the Load Level Instance node
5. Compile, Save, and then press Play again.

Results: At the cut in the nav on the floor out in front, there is no green double arrow going across it. However, if you look at the center of the MainLevel's floor, you'll see the green double arrow right there.

Expected: In the center of the floor you spawned in there is also a cut in the nav, but there is no navlink across it.
