How to insert a link in Blocks type text

hi,
I am trying to insert a (external) link in a blocks modul (type: text). in the editor I click on the link symbol in the pop-up bar (screenshot 1). Then a window opens (screenshot 2) where i can only fill in a title, but no url. After clicking “Insert”. Nothing changes. Whats wrong? Why is this in in the Blocks modul not working like in the regular textarea-fields, where it displays as:
(link: https://mylink.com/yyy text: myText)


Thanks

Hm, that is strange, it should look like this (as it does in my Starterkit)

What’s your exact Kirby version? Does this happen after an update? Is that a custom block type?

Kirby version: 4.0.1
cant really tell for sure, when this problem occurred, but i recently did update to kirby 4. So probably yes. no it is not a custom block type.

fields:
  text:
          label: Inhalt
          type: blocks
          fieldsets:
            heading:
              extends: blocks/heading
              fields:
                level:
                  default: "h2"
                  options:
                    - h2
                    - h3
                    - h4
            - text
            - list
            - image
            - video

Please update to the latest version 4.0.3 just in case.

Make sure to also delete the media folder and the cache folder afterwards.

did that! No improvement.
How do i check if it is definetly not a custom block type?

Please check if it is an issue with a plugin. Which ones are you using?

So you did not develop the website?

I had a not kirby 4 updated version of kirby-link-field installed.

Thanks a lot!
