Hello, very sorry for my late reply.
It sounds like perhaps your themes are overwriting the styling of the bullets, or do not have any styling defined.
To the OP (original poster): From your link, I can see your theme is not styling bullets. You’ll want to add some custom css to your site to define the bullets. You may either use a custom css option in your theme (if the theme provides one), or you may download a plugin which allows custom css to be added to your site.
Once you’ve decided on the implementation; you may add the following rule to the stylesheet:
div#main-content-with-sidebar ul li {
list-style-type: disc;
}
That will style the list items with a bullet.
