I am not quite sure about the approach that you use in order to hide/show menu items depending on the different user roles but I can suggest few post where a very similar functionality is implemented. For example the following post explains in details how you can achieve the desired logic: Can i hide/ show asp:Menu items based on role?
Since this article is related to the asp menu control, however, I would also suggest that you use any of the properties described in the following help article Accessing Items
to find the menu items that needs to be hidden/shown when a user logs as a different role.
