How to use the same styles on the English version of the site as on the Russian version?

Question

WordPress

Hello! Such a problem. There is such a site. On the Russian version, everything works fine, but when you switch to English, everything collapses. For example, the wrong articles are shown, the styles are off. The question is: Why are there different styles for the English version of the site, and how can I transfer the already configured styles to the English version? (ID and classes for all elements are the same)
