Thanks Rob, I'll see if I can reproduce it.
It was definitely not a case of just having the symbol selected, as one of the things I tried was to close and reopen the project.
You will undoubtedly notice that users will try ANYTHING they can in the hopes that it will work. This can lead to some very superstitious behavior. It's root cause though is not understanding how it functions, and of course some grasping at straws.
The whole way the Product Attributes spreadsheet works and the difference between it and attributes in settings is REALLY opaque, and completely non-discoverable. Given the complete lack of documentation for SD, (a handful of short videos and this forum are NOT documentation) the GUI needs to be EXTRA discoverable. The difference between type and use of attributes on the settings tab vs. the Product attributes tab should have a note written on the GUI or a pop up tool tip.
The GUI in general could use more tool tips. And AT A MINIMUM there should be a help file that explains every Menu choice, and ideally have examples or explanation of WHEN to use the feature. It is nice that we can chat with you and the other SD folks, IF you're on at the same time, but that should be supplemental not a necessity.
One last note about the Product Attributes tab,
