@kubazabran Thanks for your message.
Whereas Google typically uses the title and meta description from the page’s metadata for indexing, this is not always the case. Google will sometimes modify or ignore the title and meta description when it sees fit, as well as sometimes adding the brand or site name to the end of your title.
This behavior is not due to the plugin not functioning as expected, but rather is due to Google using another value for the title and meta description that it indexes, as it’s algorithm has concluded that there is a better version to index. We have additional information on this topic available at the following links: Google Shows Different Titles For My Site and Google Shows The Wrong Meta Description For My Site.
?If Google is ignoring the title or meta description you have created for a page and creating it’s own based off the page’s content, we would recommend creating new ones that reflect the page’s content. Please refer to the aforementioned articles as they include recommendations for crafting a page title which will help increase the likelihood that Google will use the title and meta description that you specified, instead of it’s modified version.
Additionally, we have a guide on how to write clean and meaningful meta description for your pages and posts by following the steps it outlines: How To Create The Right Meta Description.
