The reason it double scans in most leto users is that you have color tags on your name and your ispc is set to 0 or 2. When logon to GS, it reloads your char, setting the ispc to 1.(original setting)
From there, its like its a different character, so The filter re scans your char. So for all of you that just want 1 scan, Take the colors tags off and voilÃ??? . Hope this helps.
