Solarwinds sending the date twice to the syslog

Hello Guys!

We have 3 Windows 2012 Servers with Solarwinds Log Forwarder installed. They are all with the same version, 1.1.19 but for 2 servers (dcs1, dcs2) the date at the beginning of the log appears 2x (attachment Solarwinds Ticket.png) while the other server appears norma (dcs4)l, with only one date.
Do you know what may be happening? Is it some configuration?
