Blog Post Galleries are Indented

The blog side of the highend theme has always been a struggle for me. Is there a page builder I should be using? I have always used the default gutenberg block editor as it seems WP Bakery is for page only and not posts.

I digress. The specific issue I am having right now is that I added the following custom css to fix indentation of bulleted lists, and have them be properly formatted formatted on the page. The problem is that image galleries seem to be treated the same as lists and are also being indented.

#main-content ul li,
#main-content ol li {
margin-left: 25px;
}

attached is an example of the indented image galleries. Can be seen live here:
