Object Manipulator breaks interaction...

Greetings,

New to MRTK. I have been working on a project that includes a MRTK VR rig. When I play the project in Unity, a start UI pops up. I press the start button and then I am able to enter the next scene. This works if I do not add an object with a Object Manipulator component. Once I have one present, even if deactivated, I am not able to interact with the start button. Anyone ever experience this? What could be the cause.

Thank you.
