Just checked in Bridge and it shows the expected 480 photos
There are a number of things that can cause files to not import. They may have already been imported to a different folder, they may be from a new camera model not supported, an unsupported file type (must be raw, DNG, JPEG, TIFF, PSD or PNG), or in a subfolder. LR also supports most video file formats, but not all. Try selecting the below options. If that doesn't work tell us the file type and camera model of the 106 missing files.
ok, so I check I was importing everything ok and yes, its looks spot on.. what I have found is that when I try to import files for example photo.DNG and photo.jpg lightroom was only importing the DNG file. Normally I dont mix JPG and DNG in the same folder so that's why i didn't come across this issue before. I've done some testing and even if you have different photos with the same name but different file extension Lightoom appears to ignore the JPG file!
I've moved the files into sub folders DNG and JPG folder and boom! ive got the 480 images appear in my catalog

Your JPEGs are being treated as sidecars, thus being ignored. Configure your Lr preferences as shown below. This will treat the JPEG as a separate file.
