Editing, corrections, and filling out the wiki and knowledge base

There is a problem with adding from the knowledge base (hero specialization, faction, class, skills, etc., etc.). If you first select the game Heroes V, and the specialization from the add-on Lords or Chieftains, it does not appear in the search, and the same applies to everything scattered across the add-ons. This needs to be reflected in the search somehow. If you initially select the add-on Lords game, then you can't even choose a class, only Runic Priest.

I wouldn't have been able to create the hero Agbeth if I had selected the add-on Chieftains game, to which he exclusively belongs. https://heroesworld.ru/kb/hero/heroes-5/agbeth/

In the game, there are two Railags with different specializations and skills, but here it says the name is already in the web address. This should also be addressed somehow.
