There is not enough information in your posting to help you.
I don't know what the door itself looks like (without 'attachments', whatever those are), where the attachments are located in relation to the door, so I am unable to read anything from the screenshot because I have no idea what this is supposed to look like.
Its a planar door thing with a normal map on it, there's nothing more I can read from this. The shapes you have circled are not supposed to be there? You used the 'match by mesh name' feature. Are the meshes in your highres/ lowres files named correctly?
