"Last changed by" is updating the changed by name of the parent page, but not the date

[kevrl]

Describe the bug
When creating a sub page to a page in Nextcloud Collectives it will have a timestamp with the last edit like this: "Last changed by kevrl seconds ago".
the parent page to the sub page will have it's name updated to whoever edited or created this new sub page.
Example:
If I create a new sub page on an already existing page that have been edited by someone else, then my name will show up as "last changed by" but the timestamp will be unchanged for the parent page.

To Reproduce
Steps to reproduce the behavior:

1. Open up Nextcloud Collectives
2. Select a collective
3. Select an existing page (That has been last changed by some other user than you)
4. Press the "+" symbol to the right of the page name to create a sub page.
5. Write anything in the new page
6. Save
7. Go to parent page
8. Check the "last changed by"

Expected behavior
I would expect that one of the following would happen:
A) The Name and Date of the parent page should not be updated at all
B) The Name and Date of the parent page should both be updated.

In the latest version (2.10.1 running in Nextcloud 29.0.0) even the name is missing now. None of my documents has any name at all and the date is always referring to the creation date of the document and not to the last update.
