Ruling the Fire Nation has everything to do with it. These numbers are called regnal numbers for a reason. Fire Lord Zuko's mother was never Fire Lady regnant (because she had no hereditary claim to the title, but because she was married to the Fire Lord she could have claimed the title of Fire Lady consort, though). If there was no Fire Lady Ursa I, how could there possibly be a Fire Lady Ursa II?

It's the same like Americans calling their children John Jones III. They have absolutely no historical, hereditary or legal claim to the regnal number but certain American government institutions are silly enough to accept them and don't ask any questions even though they should.

Regnal numbers can only be used by monarchs, not by peers or knights, although after the creation of a title successive holders of the title use numbers to identify themselves as individuals (for example: the Rt. Hon. John X., 1st Earl of Y, succeeded by the Rt. Hon. George X., 2nd Earl of Y etc.).
