Dentalia Theme Problem!

Hello, I’m looking for a solution! I updated my wordpress so I have the 5.8 version. When I tried to update my Dentalia Theme to 2.1 I cannot do it, because when I scroll my page the update is present again…Someone with my problem?
Thank you

When you update the theme, your content should stay intact. But before updating, it is recommended to make a full backup of your website, just in case anything goes wrong.

This was not the problem…Update was impossible, doing that. I solved doing a manual adding of the plugin…but thank you for your support!
