Read this post, you have the same problem. Both files 1.dxf and 2.dxf have a block definition named "*U1" that comes from a dynamic block, when you try to merge them into the same document one overwrites the other. You need to rename them first, this library does not support dynamic blocks.

How to rename the blocks using this library, Using Block.Name="xxx" throw exception " "Blocks for internal use cannot be renamed."
