Navmesh and Buildprofile warnings everytime I launch Unity 6.0000.25f1

Every time I open Unity 6 with a blank project or my work project i receive these 3 Navmesh menu warnings, and then a build profile warning. Anyone know a fix for these or have these been reported as bugs already?

Cannot add menu item ‘GameObject/AI/NavMesh Surface’ for method ‘UnityEditor.AI.NavMeshSurfaceEditor.CreateNavMeshSurface’ because a menu item with the same name already exists.

Failed to load build profile from Library/BuildProfiles/PlatformProfile…
