Welcome. the geometry in your model is wrapped up as a component. In fact, it is double wrapped which it probably doesn't need to be. You can open the "wrapper" by double clicking on it with the Select tool. You'll need to do that twice to get in to the geometry itself. I would be inclined to explode the outer wrapper and leave only a single one. You can right click on the component and choose Explode.
