URL links looks different?

How come that URL links looks different? What am I doing wrong? If I use the share button in Safari, sometimes the link in Agenda is a small “box” and sometimes it’s just a text link.

I prefer the box type, and how to do to get that?

What I did: Used the share button in Safari

What happened: Inserts a regular text link

What I expected: A small box :slight_smile:

Things that might be helpful to know (Agenda version, OS and model, etc):
Agenda 11
Safari 14

The upper one happens when you share as a webarchive, the lower one if you simply share as a URL.
