Dynamic Obstacle required for obstacle area class.. but it blocks pathing

I’m trying to make it so my static meshes paint nav modification, of the Obstacle class - so my AI will walk through it only when the path is much shorter/it’s the only option

The problem is, Dynamic Obstacle is required to be on for the Area Class to be painted… and if it’s on, it removes the navigation… including the obstacle.

So I can add a cylinder or cube for the nav modifcation, offset it, and see it affecting stuff beside my tile… but the tile itself will have NO nav, no even obstacle

And if I unset dynamic obstacle, the red “avoid” area disappears

This is really annoying. Any solutions?
