So there are two motion logic blueprints. Faceware Live Link plugin has its own motion logic blueprint as well as Glassbox. Looks like you are trying to use the Glassbox motion logic blueprint with the faceware one. If you go to the Faceware Unreal course on here, download the zip folder, it should be in there. The motion logic bp labeled FWLL is the faceware one, fyi.
