We both provided you with suggested switches which we had found worked, both I think available from SF, but not the same model of switch. SF do sell a number of different dimmer switches, I chose and gave you the link to the one I bought, which works fine and which was able to automatically decide whether to use + or - triggering.
As I explained - finding lamps and switches which play nicely together is a bit of a nightmare, that is why I provided a link to the switch and details of the lamps, via the thread I linked to.
