LOD Group is not properly set when changing the setting in the static mesh editor. When the LOD Group is changed and the confirmation of overwrite message is cancelled it will still set the LOD Group to the newly selected one rather than defaulting back to the original set LOD Group.
1. Open any static Mesh
2. Change the LOD Group to any of the options in the drop-down
3. A confirmation will pop up.
4. Choose "No"
Results: The LOD Group will set to the one in the drop down even though "No" was selected in the Overwrite confirmation message.
Expected: When changing the LOD Group and selecting "No" in the confirmation of overwrite message the LOD Group should default back to the previously set LOD Group.
