Short Code Text Very Small

I am using the shortcode to display select posts on a page of mine, and all of the text is very small. I looked into the CSS and I found through the inspector on chrome the following parts of CSS has specific code telling the size of the text:

.rpwe-block
.rpwe-time
.rpwe-summary

With the rpwe-time and summary classes I can put a “!important” tag to over ride the text size but for the post title, which uses rpwe-block, it already is using a “!important” tag and specifies size 12px, so I can’t over ride that with custom CSS.

So where can I go inside the plugin to adjust these sizes? I can’t find any way to be able to adjust the sizes except for custom css, and that doesn’t work for the post tile.
