Yes,
do adjust the the ejector at the front to clear the slot in in the frame.
A little filing of the round "nose" is usually all it takes; you should not need a hammer to get the ejector in, but a little push with a chopstick may be needed at the rear of the ejector, to get the narrow ejector to seat in its groove.
Sometimes the round projection does not align with the hole in the receiver, and a little filing on the ejector is in order to get it to seat- but don't go too far, and keep it square- or it will pop back out when fired.

The ejector must move freely at the front where it sticks into the bolt path, when the "tab" is pushed by hand(or stick) from the inside; I suspect your ejector is caught and not moving "in" fully so it does not make contact with the empty case as it should.
