I saw that, and the instructions are wrong as they tell you to directly use the base {{Sticker }} definition which is against policy, and causing the 845 error
if you look at the {{Native American}} template, it show that it is both a Project Box and a Sticker, which is most likely incorrect and the result of a quick attempt to make it a sticker... on the template page it displays the normal project box info, as well as a sticker box, but when used on a profile, only the project box info displays.
to me, the {{Native Americans}} template needs to be split in two, adding a {{Native Americans Project}} that uses all the Project Box code, and leave the {{Native Americans}} with only the sticker code. this way all existing profiles using {{Native Americans}} are basically good, but should be reviewed and moved below the bio line. any profile that is project managed/protected would change to {{Native Americans Project}} and stay above the bio line.
