It looks like you have used some other utility to edit your images, and this utility didn't understand the makernote format so things were messed up somewhat when the image was rewritten. This is common, since the makernote format is proprietary. You can use the -m option to write these files with exiftool, but you should be aware that some makernote information may be lost. This information is not crutial, but sometimes it is useful to know the camera-specific settings that were used to take a picture.
