Page Analysis not working

Help Please!

I’m pretty new to wordpress and this is killing my brain. I’m running a wordpress template called Modern Interior by Mojo. I’ve instlled Yoast and filled in all of the settings. However, my page analysis is showing red and orange dots on items related to content.

if you go to my pages (for example http://www.afterimageseattle.com/portraits/) you can clearly see that there are images and content there… but does Yoast simply not detect them because they are in the sliders and being updated by the theme? Should I even care what this analysis says?

Thanks

A meta description has been specified, but it does not contain the target keyword / phrase.
The specified meta description is over 140 characters, reducing it will ensure the entire description is visible. The available space is shorter than the usual 155 characters because Google will also include the publication date in the snippet.
No outbound links appear in this page, consider adding some as appropriate.
No subheading tags (like an H2) appear in the copy.
