Can't teleport in Forest generated using Procedural Foliage Spawner

Once I generate the forest I can’t teleport anywhere in it even if the trees are far apart. It’s almost like it’s creating all kinds of colliders I can’t see. When I look at the tree static mesh it has a tiny collider on the trunk. The NavMeshBoundsVolume seems to show I can’t navigate all around and should have no problems (all green). If I remove the Spawner (and the trees) I can teleport completely normally on the landscape. I’m using 4.25 with the StaticMeshFoliage.
