Workstations disappear from list

Workstations disappear from list

I did a search and could not find anything on this. When I do a manual scan of a workstation that was not found in the scan, it shows it found it and all the stats. If i do another manual scan, the previous one is then lost. Not all of the workstations are being saved. How can this be fixed. Find below some screen shots I uploaded to show what I mean.


Notice how the first workstation is not seen in the 2nd and vice versa. HELP PLZ
