Can't display galleries after updating to WP 3.8.1

I am using the Sidewinder theme from GraphPaper Press (but I have a similar issue with several other themes I’ve just tried). My website is https://amandalarge.com.

Before I updated to WordPress 3.8.1, the theme provided me with the option to have a static homepage with a number of galleries displayed. Clicking on the ‘enter gallery’ text on the images on the homepage led you the image galleries. My blog was on a separate page at https://www.amandalarge.com/?page_id=225.

Since the WordPress update, I no longer have the option to have my latest galleries on my static homepage. Instead, I get the featured image from my 4 latest blog posts, and clicking on ‘enter gallery’ leads to the actual blog posts.

I can still access my image galleries through the drop-down menu at the top-right of the site, but I would like them to be represented visually on the landing page, like they used to be.

There are currently two places I can set my static webpage:1) a sidewinder-specific dashboard item; 2) the ‘customize’ option under ‘Appearance’.

When on the sidewinder-specific option, I can still see the ‘use latest galleries’ option (https://www.dropbox.com/s/g5brqcmohr53j0p/Screen%20Shot%202014-02-14%20at%205.14.35%20PM.png) ,
but it seems to be overriden by WordPress’ ‘customize’ menu, which doesn’t provide the ‘latest galleries’ option (https://www.dropbox.com/s/cf70oq98sluol57/Screen%20Shot%202014-02-14%20at%205.57.18%20PM.png).

I do not believe this is an issue with the Sidewinder theme itself, as my partner uses exactly the same theme as I do, is still on WP 3.3.2 and is not having the same problems. We are using different hosts, though. Also, as I previously mentioned, I have tested switching to different portfolio themes and am having similar issues.

I hope I explained that clearly enough! Any suggestions as to how I could get the galleries back on the landing page would be much appreciated.
