web form public access

Hi, 

I have a similar issue.  As per your note, I am trying to change “Guest User Permission” on Account, Lead or Product object as defined in (step 4 - E as defined in first link below)

However, I am not able make “read access”
Below screen shows that most of the standard and custom objects do not have access
