Orginal date and DTDigitized are not same
original datetime is the 0x9003 field. and that is include and shown if you enabled the "Picture (EXIF) - Date" column
0x9003 was chosen since some cameras do not fill the 0x9004 field.
But they are almost the same
0x9003 - For a digital still camera, this is the date and time the picture was taken or recorded.
0x9004 - The date and time when the image was stored as digital data. (usually the same as 0x9003)
PS: sometimes EXIF "Dimensions" are not shown in column (even after 'updating) - even though the data is present in the jpg info
To get the EXIF Dimensions is uses the EXIF field 0xA002 and 0xA003, Are you sure that that image has them.. ?
There is also a column called "Picture (IMG) - Dimensions" this will get the dimensions from the JPG file it self. not from EXIF data.
