It could be the ejector, could be with the hammer, loader arms or poss safety.
Can you get the screw removed for the lever to be taken out of the gun, then take the bolt completely out. It will be easier to find the problem. The ejector is placed on the inside of the receiver but is to stay in place when cycling the bolt. Sometimes it messes up or was placed inside incorrectly. So pay attention to it as you extract the bolt from the rifle. It will drop out when you remove the bolt.
Use the manual to reorient it. they are about $40 if it is broken.
