Problems with MapMagic 2 objects and splines

Just got MapMagic 2 and its three addons; Objects, Biomes, and Splines. When I import MapMagic 2 everything is fine, and also after I import Biomes it's fine.

When I try to import the Splines or Object it immediately sends out a lot of errors (22 of them). They all seem to be related to just not being able to convert Dens.Tools.Vector2D to UnityEngine.Vecotr3. Link to errors image: https://ibb.co/rc3Bb2k

Don't really know how I can help you replicate this, all i did was import them into my project. I even tried a blank new project as well. I also tried re-downloading them all in case it was just a bad download.

I am using Unity 2019.3.13f1 and on a Windows 10 computer. and I am using MapMagic 2.0.3. Also, the version of the 3 addons are all 2.0.2, which I can't seem to find an update to any of these, so I believe they are all the latest version.
