If a journal text is marked as wrong after it has been signed, it is possible to hide it in the timeline.

Go to Show in the timeline, then Journal text - Text states - and check (or remove the checkmark depending on what you want to see ) in the box Wrong.

To mark a text as wrong click on the pencil in the signed timeline and press Mark as wrong

The system will give a pop-up warning, asking if you are sure you want to remove the signed document.

This is how the info will show in the timeline.
