IIRC this shifter has a trim feature for the big ring's index position. Could it be that this is what you are thinking is the full indexing click? The trim feature will be less distinctive in feel and sound. Have you done the detached cable held by hand while moving the shifter through it's range yet?
The lack of a cable tension adjuster is just stupid set up. Andy
