Those appear to be Font Awesome elements that are not loading, meaning that the Font Awesome files are either missing or not enqueued properly.
Since that is a commercial theme, we ask that you please go to their official support channel, so you can get support from the people who know it best: https://themeforest.net/item/medical-directory-hospitals-doctors-listing-theme/14755967/support
Forum volunteers are not given access to commercial products, so they would not know why it is not working properly. Other community members who may have faced your issue might be able to help you but your best bet is your product’s developer. Keep in mind we encourage you to use the official support venues, as it allows the developers to be aware of issues with their code and gives back to the community in a more robust way.

Thank you very much very kind, I solved by deleting the theme in FTP and then reinstalled from the wordpress control panel. We see that those who installed it have skipped files. Good day and thanks again.
