Custom ECB menu not appearing in other columns, but appears in Title column

I have created an element/custom action and activated it in my list.

However, it only appears in the Title column

but when I edit other column in SPD to show the dropdown, it doesnt show my custom ECB menu. it only shows the 5 default menus (View Item, Edit Item, Alert Me, Manage Permissions, Delete Item)

how to fix this?

I want to insert the custom ECB menu in a column with type People Picker
