Cannot exit landscape sculpt mode (MAC)

Using Unreal Engine 4.4.1

Operating System: OSX 10.9.4

Can enter landscape sculpt mode, edit the terrain, but when I attempt to exit sculpt mode I cannot. I have attempted to select one of the other landscape modes, and I have also clicked on the rest of the UI, to no avail. .The System Specs are Attached

Hi ,

Does this occur on a blank project with no additional content. Additionally, are you using the launcher or source (github) build?
