How to delete a entry in favorite?

Hi, I have added a favorite (‘Activities’) 2 times by mistake. How can I remove one of them ?

What’s the problem under the Menu Options,
using the - button from the list of actions
after you have selected one entry in the list ?

Thank you, I have miss it, as it is called Menu. Why is it called ‘Menu’ ? It is not a menu, it should be named ‘Favorite’. Even in the Listary dialog on the screenshot in my 1st post it is named Favorite.
