Okay I am going to go out on a limb this is the situation at the start of the turn you are talking about NOT after you have moved units or turn 1?
The contact details are updated each turn not during it AFAIK.
Otherwise suggest you post the saved game & someone may look at it.
As all I do is look at out of contact units & follow the rules to bring them back into contact which works thats all I know as its all I need to.

I would say though & may well be wrong as just follow my gut now that units can sometimes maintain contact at longer range for a turn or 2 especially if trained to work independently like scouts.
