Yes, Matias nomenclature is somewhat flawed.
They have a loud, clicky tactile which I think is called "Matias Click" that goes into their "Tactile Pro" keyboard. It's not simply a tactile, it's a clicky tactile, but you might not know that from the keyboard name.
Then, I think that they have a dampened tactile called "Quiet Click," which doesn't click as the click is disabled. You'll notice there's no click in this switch, but it's called "Quiet Click." Should be called "Quiet Tactile."
