To rectify this issue, a "fly" is added to a mortice in the tumbler. The "fly" pushes the "sear" downward, as the 1/2 cock notch rotates past the "sear".
Check to see if there's a "fly" in the tumbler. If there is a "fly" in the tumbler, make sure the "fly" is tall enuff, to push the "sear" downward, far enuff to clear the 1/2 cock notch. Make sure the "fly" is free to move, and isn't stuck in it's retracted position.
