How to remove caption next to title from Google search results?

Question

Google

Some titles in the Google search results for my site have extra text added with a hyphen, as in the picture.
The site is based on the opencart engine, each page has a title and a single h1.
Where does such a signature come from and how to remove it?
UPD - the source code of the page is clean, in the meta-information, and in general, there is no “extra phrase” anywhere

Template path: /catalog/view/theme/.../template/common/header.tpl

<title><?php echo $title; ?> - Бегущая строка</title>

Look for a meta tag like this

<meta property="og:title" content="Табло курсов валют - Бегущая строка" />
