If a layer rule is created to exclude any feature with specific text in the name, it will also exclude any feature with a default name that includes a space. (Sketch 1, Curve 2, etc) Renaming the feature will allow the rule to work correctly because renaming forces you to not use spaces. As we all know, CREO does not like spaces. However CREO does not follow its own rules for default names for sketches and many other features.
Either fix the rules so that the default name can be read or fix the default names. As I am sure you know, everyone would like to see CREO accept spaces as part of a name.
