Mod 5.5 is everywhere in the wiki and in the knowledge base, but it's a mod, not an official game, and it duplicates everything. Regarding those sets that I underlined, I'm not sure they're from this mod, I just assumed so because it's displayed there. And those characteristics on the artifacts, we'll need to double-check all of them later. There's nothing like that on the rune axe. And add bonuses from the partial set, from the full set, and for a specific race.
There's technically no duplication; there's inheritance of all parameters according to the sequence of add-ons and the mod (each subsequent add-on or mod can override the parameters of the base card without modifying it).
Original -> Hammers of Fate -> Tribes of the East -> Heroes 5.5
This is the base card https://heroesworld.ru/kb/contribute/artifact/79/
And this is the derivative https://heroesworld.ru/kb/contribute/artifact/241/
The axe card did indeed have an incorrect Russian description for Hammers of Fate, although the parameters were correct, and the English description was correct; I fixed the Russian one. Anyway, as I said, there are clearly errors — there's too much data in this knowledge base, everything needs to be rechecked.
For horizontal display, I added a separate "Card Grid" mode and applied it to your page https://heroesworld.ru/wiki/history/compare/21980/121322160/?toPostId=121322174
