  • is it the default list filter ? do you face this issue with other users? – Mohamed El-Qassas MVP Aug 13 '17 at 7:10
  • Default list. No other uses don't encounter this. Deleted the user account on active directory and re added it. Still occurs on the computer or user that user accesses. – devnation Aug 21 '17 at 16:46
