Confusing wall problems, help?

[NylePudding]

Recently I have been working on a map, but after a while I decided to start over, so I made a completely new map file. To save time I just renamed my original map, and changed the name of my new map to what the original map used to be called. I did this so then I didn't have to make a completely new custom story.

This is when it gets weird, when I try to test the map in Amnesia the walls are in the same position of the old map, but the items are in the positions of my new map. I have deleted my old map so I can't see why or how this is happening.

Please tell me if you don't understand what I mean, and I will re-explain.

Thank you.
