Sorry about that, my message wasn't complete. In the lvl 1 training I was trying to align the check mark associated with "Is Organization" to G1 Region where the Category is labeled as Organization. The check list seems u-editable and remained on the --- Geo Hierarchy --- line.
Unfortunately, that setting is not able to be changed. The "organisation' list is an autogenerated list when a model is created and the list cannot be deleted. The only way to now align with the Level 1 training is to rename the list and use it in the hierarchy, but if you have already created the hierarchies, personally, I wouldn't bother. The check box is a hang over from way back and as far as I know it is not used for anything, and it definitely won't affect your ability to pass Level 1
