It sounds like you have a "ratchet" shifter, it clicks, but the clicks aren't meant to select a specific gear in the same way an indexed shifter does, where each click position references a specific sprocket on the rear cassette.
As with a friction shifter, you just move the shift lever to select a gear that feels right, then, if necessary, trim it so that the chain runs smoothly and quietly over the sprockets.
