Stuck in Open Loop Cold

This seems to happen most of the time I upload a map before a cold start.

I try to datalog but the AF ratio stays at 10.70 and the fuel status says "open loop-cold". After about 10 min of driving it still says the same thing. If I turn off the car then turn it back on it reads like how it normally would.

Does this mean my O2 sensor is going out? It has been cold here could this have something to do with this?

Did you ever find a solution to this problem? I have the exact same issue with my RSX-S where fuel status is stuck in open loop cold (on my KPro) forever until I restart the car, and I don't want to go buy a new primary o2 if I don't have to.
