Hi @scorp_pl),
Thank you for appreciating the plugin, however it is sad to see 3 stars from your side. It made you do this because of this little inconvenience in your environment with Twitter Icon. But, I am here along with my technical team to look into the underlying issue for you.
Since the issue you are having is not replicated here and is believed to be caused by Theme or some other factor. That can be investigated and resolved with a personalized solution. You are requested to ping us at our support form for it.
Looking forward!
