Wrong Chinese calendar

These coins have been set to the Republic of China calendar, which is erroneous. I have attempted to change it to the correct calendar (Puyi Emperor) but that calendar is also wrong. Also, the Emperor is known as Hsüan-Tung on the coins and perhaps the name of the calendar should be changed to that (Puyi is his personal name)
The reign of Hsüan-Tung begins on 1908.
