If I press the French flag icon with WPML installed, I get unstyled 404 page

So I’ve got Enfold customized via child theme. It’s got my logo, colors, all that jazz. All is well. On the front page, if I click the French flag next to the menu, it throws me to a French 404 page. Now, there’s no French equivalent of my front page right now, so I expected a 404, that’s fine. But what I didn’t expect was the Enfold logo re-appearing with default colors. As shown here:

My main menu and footer contents are visible, but the styling is different. If I click on the British flag, I get sent back to version of Enfold that has all my logo and styles.

So I’m wondering two things: first, why is this happening? Second, what is the best way you recommend fixing this? Do I have to hard-code my custom logo somewhere, in case this happen? I wouldn’t want Enfold’s default logo and styling to appear at any point, regardless of error.

Thanks!
