Permission problem in TYPO3 v8 for non admin users

Users in the editor group ("Redakteure") are not allowed to edit two content elements, the two bottom ones, which were created by me, the admin. The users in the group are allowed to edit their own content element, the top one. The creator of the page is a member of the editor group and the permissions say they should be allowed to edit it, but the edit button is not visible for them. "Restrict editing by non-Admins" is not active on these two elements.

How can I give a user or group edit permissions to all content elements on one page?

User is in the group:

You are missing some permissions in the backend usergroup «Redakteure». Use the list module on page [0] and edit the backend usergroup «Redakteure».

In tab «Access Lists» at bottom allow the content elements «Table» and «Regular Text Element»:

• Explicitly allow/deny field values: Page Content: Type: Text
• allow/deny field values: Page Content: Type: Table
