Not certain where to even point this.
But as seen in the screens, your maps do not show the same things, especially if you look at the portals, 1 show 2 portals, the other one does not. This itself should be some sort of duplicate of the map.
The has portal box creates a portal to cape and is the only REAL way of getting into your map from cape, and back to cape again from your map. So if it's a stand alone map it must have the "Has portal" checked. Also keep in mind that a map that you do make in the game from the terrains folders work as one map. And if you export the very same map YET another portal will be created for the same map in cape.
The exported map is only really there so you can easily send the map to other users, but there's no point in just exporting for the sake of exporting, so make sure you just have the actual map laying in terrains, and delete duplicates in the exports folder for the map if you aren't going to send it in a zip to someone else, then after that delete it.
Another thing clearly noticed is that some of the objects misses a material file or fails to export it, this will probably cause the map maker to skip exporting the files all together or maybe even the object group the object lies in. As mentioned above, install the said missing objects into my_objects folder again if possible and it might resolve that issue.
