I have updated to version 3.4.50.
Since then, the data field for additional information when creating or changing an appointment has been missing.
{{Additional information: EXTRAINFO}}.
I cannot enter additional information because the field does not appear in the input form.
For appointments that were created before the update, the fields and their content are displayed in the front end, but can no longer be edited in the back end.
Where do I have to change this or adapt it again?
The picture shows the Front end.
