First off, you are 3 builds back. You should upgrade to at least 4.9.2.70

Your terminology is a little confusing. The Surface tab shows what materials are attached to a figure or object. It does not have any presets. For Genesis 3 figures, material presets are located in Content library under either materials or characters.

You should consider using the DAZ Install Manager to install content. When configured properly , all your content should be available and it makes it easy to have multiple runtimes.
