Text of timeline elements not editable

Hello,

I am using the timeline to show a list of my talks.

It seems that the text of the timeline elements, including the name of the event, a link to the event, the title of the talks and sometimes a video is not editable in the admin dashboard.

When I create a new element like “03.11.2022 Lecture: Requirements Engineering” I cannot edit the text as there is no text-field shown in the timeline element editor. The same problem occurs for existing elements. All information, like title or date, can be edited except the text that is already shown in the timeline.

Why is the text-field not available?

Best regards
