Just tried, and it works fine here.
It's nothing that can be caused by the scenery, because the only way to affect Approaches is by means of the AFCAD file and, the AFCAD that comes with Geneva, doesn't include any new approaches, doesn't redefine any of the existing ones, and has the "deleteAllApproaches" flag in the "DeleteAirport" section set to FALSE, meaning it will not affect in any way the default approaches.
So, it must be some other AFCAD you installed that might have done something like this.
