Display errors and icons

Hello,

after updating wordpress to version 5.6 and to the latest version of medicare, I get icons display errors. For example, you can look at them in the url Matteo Benedetti Valentini - Polimedica Favino - Centro Medico e Fisioterapia Romanina Tor Vergata, on the left column, near phone number and email.
I get display errors in single post too, where the theme shows a big box containing avatar and author name, that shouldn’t be there. Look at Promo febbraio e marzo controllo nei - Polimedica Favino - Centro Medico e Fisioterapia Romanina Tor Vergata
Clearing custom CSS didn’t help. Uninstalling and reinstalling theme didn’t help too.
Would you say me how to fix it, please, and take note for next theme upgrade.
Thank you for helping
