That's an interesting case. ReiserFS was designed to be very robust in the face of partial data loss, allowing for a reconstruction of the file system metadata from recognizable copies embedded in the files themselves.
Thus the contents of an embedded ReiserFS image will look like lost files from the containing filesystem, if the option to reconstruct metadata is enabled.
Running man reiserfsck is advised before doing recovery on a damaged ReiserFS image. Paying particular attention to the various mentions of --rebuild-tree may be wise.
In other words there is nothing to fix, except a lack of awareness of one of the better features of ReiserFS, or perhaps a lack of a specific warning.
