Toggle icons

After updating the Atlantic theme to the latest version 1.1.4 there are new icons on the top of the posts page, representing List and Grid. Both are toggles for switching between (in my case) full photos or smaller size photos. However, both toggles seem to have the exact same function. Both switch between full pictures and a grid with smaller pictures. The List version doesn’t seem to display a list at all.

In my particular case I feel the need to be able to disable this function altogether as I show only one photo (or technically: one post) at a time. I couldn’t find this in the theme’s settings. FYI: I make use of a child-theme, which has always worked fine. My work-around solution has been to add to the child-theme’s CSS:

.blog-layout {
display: none;
}

Now the toggles are visually removed from the posts page.

Comment or advise would be much appreciated. Thanks in advance.
