Self Shadow casts shadow on itself

I'm not sure which way this one should go, but there is inconsistency with how Self Shadow works when compared to the Direcitonal Light or Point Lights.

When Self Shadow is enabled on a Directional Light the Static Mesh will no longer cast a shadow on other geometry, but will still cast a shadow onto itself, however, a point light will not cast a shadow at all, but will shadow areas that should be shadows with self shadow enabled.

See attached image for reference.

1. Open UE4
2. Drag any mesh into the scene
3. Enable Self Shadow with Dynamic Directional Light
4. Add a Point Light and disable the Direcitonal Light

Results: Self Shadow is inconsistent between Point/Directional Lights

Expected: Self Shadow should either allow shadows to be cast on itself from the light or not at all.

Mesh receive shadows but not cast
