I am using Montserrat as the text in the body of my posts.. and I have my images set to have rounded corners = 10%. When I use Elementor the featured image and other images have rounded corners.. and the font is definitely Montserrat. 

However, when I use the WP editor.. my featured images are cut off on the right side.  There are no rounded corners on the right side.. nor are the corners rounded on any of the other images.. see this page: https://nestfeathering.com/improve-your-curb-appeal/

Also.. the font on that page does NOT look like Montserrat.. even though that is the font I have set in the customizer.

I even went into the css and set the default font for the body to Montserrat.

The following page is using Elementor.. you can see the difference in the font as well as the images.. https://nestfeathering.com/outdoor-decor-for-patio/ I am much happier with the way my site looks using Elementor.. but my web guy advised me to get rid of it.  He said it is slowing my site down.  But, my Soledad theme features do not seem to work as well in the WP editor.

Is this common.. or is there something I do not have setup properly?

Thank You,
