EditorGUILayout.Popup() ignores repetitive Strings in the Array

So i have been making a Popup in OnInspectorGUI() , and wanted to display a dynamic popup, and when i pass a repetitive string for the array, it only displays 1 of them, here is an example:

 int index = EditorGUILayout.Popup("My Popup",myScript.index,new string[] {"Content","Content"});

Here i have a String Array, that has the length of 2, and has "Content" and "Content" in it, and the Popup only displays one "Content".

Is there any way to make/force it to display both? Thanks.
