Non accessible pages, also duplicates

Hi,
please help us - we are moving/deleting some pages, but there are some of them, which are not accessible. I can find them in the document-index /Main/AllDocs, but when i click on them (or try to delete them directly from there), I’ll get “Document cannot be found”.

I also tried to use this velocity script: Unable to delete a page that is not accessible (URL) - #7 by scharette
But this show: exists: $false

In a xar-Export it looks like this:

And also in the database, there are multiple xwikidocs-Entries:

xwd_comment starts with “Copied from…” - so I’m sure some colleagues already tried some things, too… (and i think initially created in an older version)

Is there a way to get rid of them? I have a backup of the content of these pages, so i can easily recreate them. But these pages caused duplicates in the navigation tree (Winclient/WinClient) and after “deletion” they are still somewhere…?

XWiki-Version 13.10.3

If you need any additional information, please let me know.

Thanks,
Gerd

Any idea? Or can i delete those documents (we have 3 of them) directly in the database?

Thanks
Gerd
