The campaigns in the original Heroes of Might and Magic V are missing. Auto-translated

Hello, this is my first time on your site, but I couldn't find a topic specifically for problems (not related to the technical part). 1) I have a licensed version. 2) I searched a lot, but didn't find a similar problem. 3) The problem is not related to Ubisoft. I clearly remember (although quite a few years have passed) that in the original Heroes of Might and Magic V, there was a list of campaigns for all factions, and they started with the Necropolis (not to be confused with the "Will of Ashan" campaign), as it starts quite differently. For example: - In the first mission, you need to capture an elven town and defeat their hero. - In the second mission, you were facing wizards, and you had to take some artifact and capture an outpost (BUT this is not certain). I searched through all the files, checked for everything possible, but found nothing.
