By making catrips selectable the builder is treating them as uttility powers now. This causes issues for any Hybrid Wizard / xyz. As long as any cantrip is selected the character is forced to choose his first utility from the "xyz" class instead of being able to choose from either class. Deselecting all cantrip selections enables you to choose from either class as normal. If you pick any cantrip after picking a Wizard 2nd level utility you get the orange house-rule indicator.
