How to reproduce

• Go to the demo : https://demo.ametys.org/nightly-intranet-cms/intranet/index.html
• Put a publication date on a page that has content. Example: (10/01/2023) https://demo.ametys.org/nightly-intranet-cms/preview/intranet/fr/mon-organisation/l-institution.html
• copy the page
• paste the page
• validate content

After pasting I tell myself that I don't need to touch the scheduled publication or consult it to check, I can see that the information of the date of depublication has been pasted, then I click on cancel to exit.

If I go to the CMS admin "Exploitation > Planificateur de tâche", I can see that no unpublish task has been created for the copied page

To avoid this problem, after doing the pasting. You must consult the scheduled publication of the page via the dedicated button then click on "OK" without this manipulation the unpublication task will not be created
