Under Joomla 6, I am experiencing an issue where newly created blog view menu items do not display their own assigned content, but instead load the posts of another existing blog menu.
The problem occurs consistently in multiple cases. Even if I create a new menu item and assign an empty category to it, the same existing blog content still appears. No matter which menu or category I set, the displayed list always points to the same already existing blog content.
The second issue is related to dynamic content shown on the homepage. I would like to display these items under a separate standalone menu item, also in blog view. The redirect goes to the correct URL, but the expected content does not appear there either. Instead, the content of the other blog menu is shown again.
In addition, it seems that not only the content is loaded incorrectly, but the menu context also does not switch properly. The target menu does not appear, and its colors and display settings are not applied, as if the system keeps the context of another blog menu active throughout.
Based on this behavior, the issue does not seem to be a simple category assignment problem, but rather a menu context or Itemid handling problem.
Please check what may be causing this behavior and help resolve the issue.
