[2022] Level-Scaling doesn't work with Zealots, Legendary Animals and Drengrs

Hi everyone,
my issue is this: level-scaling. It doesn't work completely. I'm playing on Aesir difficulty with Nightmarish mode on, and regular enemies and bosses from the main story arcs are ok, they scale depending on Eivor's level. But if I fight a Zealot, a lost Drengr (from Norway or England) or a Legendary Animal (from Norway or England), their power level is stationary to their default level and doesn't scale on Eivor's power level (as it should be). This fact is strange, because it happens only in England and Norway, but not in the dlc regions (Francia and Ireland), where if I fight legendary animals or optional bosses in that regions the level-scaling works correctly.
