Your photo shows a yellow spring and the related hardware that retains the actuator and the shoe to the backing plate. The back side of the retainer has a sleeve that goes through the actuator and the brake shoe. It may be possible that the hole in the shoe is too small or it has some sort of coating on it and could be binding and causing the tang to not set on the star wheel. My reference materials show a straight spring on some and others a beehive type design. The book I have calls it a return spring. I don't think it matters much except both are considerably smaller and weaker springs that would apply less pressure. My suggestion would be to do a test and remove the return spring and see where the actuator sets relative to the star.

Something I learned during my 50 years of working on this stuff. Don't throw anything away until you are finished and it works.
