The search bar width was set to “auto” which means, that it follows it's parent element. In this case the parent element was very small, so the plugin was displayed that way as well.
I've changed the width to a pixel value of “240px” (with the Theme Options -> Overall box layout -> Search box width option) , which appears to be working and is now displayed correctly.
I hope this helps!Best,
