Hello, I'm encountering a challenging issue in Umbraco Cloud and need some guidance to resolve it. After creating new 404 and 500 pages in my project, I'm can't finf a way to delete the old 404 and 500 pages. Nature of the Problem: The old 404 and 500 pages still exist in the backoffice's content section, but they are unremovable. Attempts to access them in the backoffice result in an error message indicating that the pages cannot be found. When i try to perform any action i get either:

Server error: Contact administrator, see log for full details. Failed to create blueprint from content with id 1103

or

Server error: Contact administrator, see log for full details. Failed to retrieve data for content id 1103

Troubleshooting Steps Taken: 1. Tried restarting the server. 2. Rebuild Database cache & Memory Cache 3. I have checked the Umbraco database (MsSQL) and it appears that the node IDs of these pages are not listed there. 4. I have downloaded the codebase from the environment to investigate, but couldn't find any references to the said pages there, and they are not in the content section . I suspect there might be some kind of conflict or inconsistency in how Umbraco is handling these pages, especially after the template modification. * Question:* How can I remove these old 404 and 500 pages from the backoffice when they seem to be inaccessible and no longer exist in the database or codebase? Appreciate any tips or insights that could help me resolve this issue. EDIT: This is the sql-query i used to verify the nodes do not exist in db

SELECT [id]
      ,[uniqueId]
      ,[parentId]
      ,[level]
      ,[path]
      ,[sortOrder]
      ,[trashed]
      ,[nodeUser]
      ,[text]
      ,[nodeObjectType]
      ,[createDate]
FROM [dbo].[umbracoNode]
WHERE id IN (1103);
