Your new bobbins may not sit right in the bobbin area, too high. Also, if you roll them they may roll unevenly. Looking at them from the side you will notice that they may be askew or crooked. And sometimes the centers aren't connected to the sides; so the part that the thread winds around will rotate around separate from the sides, which means it will not work.
