From the files you posted it is obvious you did not create all the models from the base model as you said you had. Some of the feature structures are very different.
When dimensions are placed in drawings, they aren't just attached to a line, edge or point in a 2D drawing view, they are attached to specific lines, edges & points of the actual 3D model being viewed. So when a model is re-referenced, the dimensions look for those specific element ID's, and when they aren't found, the dimensions become dangling.
