Isometric map issue

What im tryng to achiev is to make a Diablo 2 world style, i downloaded Tiled and a few isometric Tilesets. For some reason im encoutering a wierd bug, for example i have a door that is divided and 2 tiles, if i select them individually and drop on my map, it works fine. but if i select them both at the same time, it wiont look right. Here is a screenshot of the issue. http://i.imgur.com/z3P4VJ9.png
