If the striker follows down, the trigger is set wrong. Insufficient sear engagement, insufficient spring pressure, engagement angles not quite right; who knows? I suspect the weight of pull screw was simply backed off too far. Sometimes, it's a fine line. When working with a trigger like this, I like to back off the weight of pull adjustment to the point the spring is not contacting at all and the trigger has to be held forward to engage. Cock the rifle (by holding the trigger forward while cocking) and see what the trigger pulls with no influence by the spring. If it takes 2 pounds to trip the trigger, it is plain that you cannot adjust lighter than that. Now, one can reduce sear engagement (probably not a great idea) or hone the contact surfaces (also not a good idea unless you have the ability to do it correctly) but the best thing is to be sure the trigger is set to a weight of pull at which it is totally reliable.
