The Navmesh Modifier Component in blueprints does not properly update a levels navmesh.

Steps to Reproduce

1. Open editor (any project)
2. Add a Navmesh Bounds Volume to level
3. Increase NBV size to 1000,1000,1000
4. Create new actor blueprint
5. Add a box collision component
6. Add a navmesh modifier component
7. Set navmesh modifier area class to null
8. compile, put a copy of blueprint into level in the navmesh
9. Go to show>navigation


Navmesh does not update based on the navmesh modifier component


Area within the box collision shows null value in the navmesh, creating an area void of any navigation.
