AX 2012: AccessLevel for an entry point (for a display menu item)

I am very new to AX (I just got access to it last week).  According to what I’ve read, the AccessLevel dropdown list of an entry point contains some or all of the following values: 
                NoAccess
                Read
                Update
                Create
                Correct
                Delete
Each value may or may not be in the list depending on certain factors.  Here is what MSDN says:
 
*****
“For example, the [AccessLevel property] drop-down list contains the Create value if, but only if, the CreatePermissions property of the menu item node under AOT> Menu Items is set to Auto, and there is a Create node under AOT> Forms> MyForm> Permissions. “
(http://msdn.microsoft.com/en-us/library/gg841928.aspx  updated May 31, 2012)

The same dual requirements would apparently apply to the values Read, Update, Correct, and Delete also (Correct has the additional requirement that the table be a valid time state table).


However, I have created a form that has only a Read node under AOT > Forms > MyForm > Permissions.  Therefore, the entry point’s drop-down list for AccessLevel should not contain the values Update, Create, Correct, or Delete… but it contains all of those.  

In fact, I can also set the permissions on the menu item such that only ReadPermissions is AUTO (with UpdatePermissions, CreatePermissions, CorrectPermissions, and DeletePermissions all set to NO), and still Update, Create, Correct, and Delete show up in the entry point’s list for AccessLevel.

PS: I can provide the full set of elements are relevant properties if needed.
