Problems like that are incredibly frustrating. What entries you make look right, but somehow the result is wrong. I usually just assume somewhere along the way the authors of the instructions forgot something incredibly basic like permissions. Because they have their system set up so that they already have them set for their user or something so they don’t have to enter them every time they work on something, so they never think about it and spell out those steps when writing help responses. While help is often well intentioned (and I always appreciate someone’s help) there’s always the opportunity for them to forget what they didn’t know at the most basic level.
