Tasklist Panel in "Agenda" view doesn't show my tasks. It can show one to-do, after turning off and on related source, but after switching view, for example to "To-do List" and back, it also disappears. All my to-dos are simple, without due date, and priorities. I have to-dos as from gmail, as from Next Cloud Server (CalDAV). They are all visible in "To-do List" view.
I'm sorry, what I considered a "tasklist panel" was actually a "item view" panel. I found a setting, showing the tasklist - and they are all there :) Please delete this "bug".
