I wrote this question as a comment to a different question I had but figured I would re-write it again as a new topic.

When I create the library feature, there's some features that get removed after the last feature I select for the library feature. As you can see in the before image I have two 3D sketches below the Boss-Extrude2. The features that I select for the library feature is the Boss-Extrude and Plane3. The after image shows that my two 3D sketches are removed. The file that is opened is still the original file. What is happening? I need these sketches for when I place my library feature.
