Sheet Index Toolbar missing icons

Hello, Sorry if this has already been addressed but if so, I cannot find an exact solution to my problem. I am trying to add cross-sections to the sheet index but am 1) not seeing the sheets being added under my drop down shown in the screenshot and 2) don't have all the icons shown in a lot of the tutorials. Any help would be appreciated.

I am using OpenRoads Designer 10.7.3.18

Thank you,

Austin
