mersenneforum.org - Odd ms/inter and ETA info on one machine

Hello, I am fairly new, one of my machines is doing this:

Instead of this, on a "normal machine":

It is my only machine with this processor:

[QUOTE]Software Version: Windows64,Prime95,v29.4,build 8

The CPU page does display an expected time: 2018-09-26 00:01

Not sure if this is a setting I need to tweak or if I can ignore it. Would be nice to see what it's doing performance wise in real time though!
