BUG: File Upload files exist changes don't reflect in filename field.
OK, so here is one I've discovered today.
Changing the properties of the "If File Exists" behaviour in the Upload Wizard if you change from "Rename existing file" to "Rename new file" the "Rename to:" field does not change from: "[ExistingFileName]_[Increment]" to "[NewFileName]_[Increment]" which it should do if it is to behave like the opposite direction.
