Time Played Reset

Hello, My ign is Fena1004 I recently noticed that my in game play time has changed to lower than what it was before. This is in the S2 PVE server. I noticed this changed on Monday August 6, 2018 but thought it was just a one day bug thing but two days later it still is lower than what it was. I got the achievement for being on for a whole day. But my play time now says 7 hours. Im not ranking up for now but I just wanted to adress this for anyone else having this problem.
