Why do social media icons disappear in nuxt?

Question

JavaScript

<script src="//ulogin.ru/js/ulogin.js"></script>
    <div class="fb-login"   data-ulogin="display=small;
                    fields=first_name,last_name,nickname,photo,photo_big;
                    optional=phone,city,country,email,sex,bdate;
                    providers=facebook;
                    callback=loginFb;">
    </div>

Good afternoon, dear developers, such a problem on the site smmtouch.store, the previous developer attached ulogin for authorization through social networks, if you make several transitions from the authorization page to the registration page, then the icons of social networks simply disappear. Above is the code from the documentation.
Each icon is implemented as a separate component, and looks like on the screenshots.




Thank you all in advance.
