Blockquote modifications not saving

I have the same problem that was mentioned earlier, but the topic was closed without anyone sharing the resolution.

I am trying to make the background of blockquotes match the background of the theme. They are defaulting to some white or gray color right now.

I have added the changes to ATO>Blockquotes and Blockquotes in Blockquotes styles.

Here is what I put for both:
color: #42834e;
padding: 1em 1em;
background: #c9f7b0;

Wordpress is just not recognizing this change no matter how many times I save and refresh the page.
