The Author Listings menu element type are not working if multiple instances are created.
Only the first instance (as Joomla order defined) is working normally. All following instances (following as joomla order is set in backend at menu manager) are working like a redirect to the first one. The settings are not loading for any of the next instances: the name, alias, user group filter...
If Joomla order is changed and a different Menu Item Type: Author Listings is listed first, all the following ones are acting like the newly set first one as well.
The frontend result menu urls (with or without SEF) are identical when multiple Author Listings menu elements are published even, obviously, those are having different itemid.
In the main menu I have now 2 different elements, both with
/index.php?option=com_content&view=author&layout=list&id=0&Itemid=128
/index.php?option=com_content&view=author&layout=list&id=0&Itemid=128
urls
But it suppose to be two elements with the following urls:
/index.php?option=com_content&view=author&layout=list&id=0&Itemid=128
/index.php?option=com_content&view=author&layout=list&id=0&Itemid=228
I also noticed that the menu url in backend is like
index.php?option=com_content&view=author&layout=list&gid[0]=2&gid[1]=8
index.php?option=com_content&view=author&layout=list&gid[0]=7
Therefore I can say that there is a bug in that "Author listing Menu Item Type" related to Joomla Site Routing in Joomla 5.
