Version: 4.0.0 Messed Up Styling!

I’m using the child theme.

After updating main theme to version 4.0.0, my page titles changed from previous style! When I go into customizer, it shows the correct padding, background color and text color in the customizer itself but the front-end does not equate to the settings (bigger padding and black text). See screenshot:

Also, the footer widget font size changed from what it was before. And where do I change the size of the font in the footer widgets? Use to be in customizer typography but gone now?

P.S. Not at all a fan of the new customizer!
