MMH5.5 - Heroes of Might and Magic 5.5

Yesterday, I tried this mod, version 16, for the first time. I enjoy large maps with a lot of monsters, as well as customizing maps before playing. I encountered the following problems: 1. In the map editor, it is impossible to add objects, heroes, artifacts, treasures, etc. - there is absolutely nothing. 2. In a newly created map, all neutral monsters are level 7 (rarely level 6), which makes it difficult to even access the most basic mines. I am playing on the most difficult level, but in the original game, this was interesting, but here it is really impossible. It is impossible to encounter neutral monsters of levels 1-5 (only if they are set to appear weekly). Does anyone know of any solutions to this?
