how to display all vpn users logged in last month

Why will FaZ report show multiple authenticated users at the same time? For example:

" 402 ","1147240089167 QHYHAP1","ssl-tunnel","2020-01-16 06:28:54","1 ","00:03:16" " 404 ","QJLLAP1 QJPWAP1","ssl-tunnel","2020-01-15 02:08:50","1 ","08:00:15" " 409 ","QLXWAP1 QXHSAP1","ssl-tunnel","2020-01-14 06:34:40","1 ","01:48:34"

Is this a FaZ error? My DataSet looks something like this and there's nothing like this with other locations where I pulled report.
