Why are all features after a combine a "child" of the combine?

Sw 2013 sp3 - I cannot delete a combine in the middle of the feature tree without ALL of the feature after the combine also being deleted, even tho there is no dependancy from any of the latter features to the combine. The parent/child relationships dialog shows everything after the combine feature to be "children" of said combine. I do not want to re create ALL of the sketches/features again. Any help / insight would be appreciated. Thanks.
