Text disapears when I write it on some parts of my drawings but not others

In some parts/areas of my drawings when I enter text in a text box it disappears when I click away. Parts of Lable arrows also are cut off when they cross into those same areas. In other areas writing text works fine. What am I doing wrong? When I turn off the layer with my drawings on it all the attempted text is visible. Is there something I need to do with my underlying SketchUp model or am I missing a step in LayOut?

Could it be you are writing text on a layer that is BELOW the layer that has drawings on it? The drawings may be covering the text up. Put text layers in LayOut on top (and I think it is a good idea to keep a single layer for text and dimensions–or a layer for each of these categories).
