Unable to Create a History Tab with a History Section in Customized RTC Work Item Presentation

I am trying to create a customized Work Item type and want to include the history tab.  Everything has been going great creating the different tabs and sections until the History tab.  I can create the History tab with no problem, but when I click on the new History tab and select "Add Section", the option(s) for "Slot" is "None".  I create a Section ID and immediately the message "Slot must not be empty" and it will not let me "Save".  I look at the other default presentations and they all use "History" with slot = "None". 

History [content shared]

     History (layout slot: <None>) [content shared]

I searched on-line but have not found anything about this.  Prior to this, I used an existing Presentation and just "Duplicated" a lot of stuff, but this time I decided to go from scratch. 

Is there a way to create the "History" tab and section without using an existing presentation??
