Setting location of NavModifierVolume in blueprints doesn't update the Nav Mesh

I have a NavMeshBoundVolume that surrounds my entire level and I need to add a NavModifierVolume to block off a certain section. The section that needs the NavModifier is generated at a random location and I have in my blueprints a way to adjust the location of my NavModifierVolume to the correct location but it doesn’t actually take away from the NavMesh.

This is how I adjust the Modifier in the blueprint.

I can see the Modifier is in the correct location, it just does not affect the NavMesh in any way.

If I bring up any of the transform tools such as the translate tool and budge the NavModifierVolume just a smidge then it will update the NavMesh, but, if I don’t manually modify the Modifier in the viewport then the NavMesh will not be affected by it.

do you have runtime generation enabled? (should be dynamic or dynamic modifiers only)

It was set to Dynamic for me
