Early Scandivanians kings are not denotated by numerals, but by patronym or epithet. E.g. Haakon the Good, Haakon Ericsson, Haakon Sigurdsson, Erik Bloodaxe, Sven Forkbeard, Svein Knutsson, Olaf Tryggvason, Harald Bluetooth, and many, many other Haralds. Numerals were given retroactively to historical and semi-legendary kings by chroniclers, or even most (in)famously by kings themselves such as Erik 1110 and Charles 1001. So there is no Björn I and the other is known as Björn at Haugi.
