PPP connections counting down the 1.st min on 2.8.19

Hi guys.

When my PPPoE server accepts connections from my users it counts down the uptime of those users from one min to 0 and then starts to count that correctly again. This is a weird bug which makes my web-based stats look inccorect.
Any of you experienced the same thing?

Sorry, it does not count down from one min back to zero, the counting down seems to start at random times.
Pluss I also noticed the uptime show by RouterOS is inaccurate.
Meassuring one random user in 2 mins I noticed 10 seconds of inaccuracy, even though I meassured his uptime starting at 0:00 …
