You said: ""Campsie, New South Wales, Australia" is probably a correct place but FTM 2012 has no information about it and can't resolve it so it leaves it unresolved"...and:
You said: " And my interpretation is that there is no such resolution as "Partially resolved"
No, that is not true. The system's new structure leaves 3 "states" for resolved:
Checkmark - fully resolved
Question mark - unresolved - does not show in heirarchical view.
No mark inside the icon - partially resolved and recognized in the heirarchical view.
This change in FTM's structure was made commensurate with the new capability for the heirarchical view and was meant as a way for people using addresses, church names, cemtery names, etc in the place fields to be recognized as resolved for purposes of the heirarchical view.
It also allows one to correct misspellings, insert county names etc, for those with addresses, churches, cemeteries in the place field.
This change was actually quite a change forward for the FTM structure - but the heirarchical view would still be better served to simply read a person's places from right to left without any reference to whether they are resolved or not resolved or partially resolved.
