Negative water production

I started a new game today and after getting all 4 systems working, went inside. Water was producing but always at negative amounts? -.7, then later it went up to -.4 but I was never able to get any O2 producing. I was thinking it was due to negative water. Bottles were being produced. I found this post and restarted the game a couple times. Then water was at 0 and finally started going up, as well as oxygen started being produced. I'm guessing the water being at negative caused no O2 from being generated. On the game restart where the water was not negative anymore, all 30 bottles were gone and it started making them again.
