Mark as read/ Unread

I know this is a small thing…but it is against normal Mac OS behaviour

Right click Mark as Read behaviour seems different.

If an item is unread and I right click on it and normally would expect to navigate to Mark --> As Read…

Instead it has in the menu data/marked there is a tick next to mark “as unread”.

Surely the description in the menubar data/marked should change to “Mark as Read” or " Mark as Unread", depending on whether it is read or not.

The current behaviour has the advantage that the menu item does not only supported checked/unchecked states but also mixed ones, e.g. if some of the items are marked, others are unmarked.
