I have the same problem after the recent updates..my hero background overlay color no longer works.
However, when in the customizer for Hero I select “Enable parallax effect (apply for first BG image only)”, the Hero background overlay works, but the slideshow plays only the first image item over and over. When I deselect “Enable parallax effect”, the background overlay disappears again but the slides function.
I see the hero background overlay color not working is already listed as an issue on github, but the parallax conflict in settings isn’t mentioned there.
