Format of Catch Box Pro Posts Has Changed

Hello, I just logged in to our blog and Catch Box Pro is displaying a new layout, with a "add block" section at the top. AND the typography in all posts, from already published posts to draft posts has changed from a san serif font to a serif font. How do we go back to the san serif fonts so all the posts match? Also the layout of the posts has changed in how the typography and pictures appears. Did Catch Themes update Catch Box Pro and not notify us? What's going on? Blog is shellyandcococreate.com
