If your using a custom map, it could have been built at -85z as the ground level like Malas! The z goes from -127 to 127 and not all maps have ground level at 0, Malas is default -85 as example! Also, you'd get more help if you gave more details, using a custom map/shard from the past always comes with issues and near impossible for anyone to help without more details! Screenshots of props doesn't do much and have to make assumptions to help! Seeing that your map is using Malas default ground level leads me to believe this custom map used malas as its starting point! Just a guess!
