Why is Mppt Low temperature cut-off with Smart Battery Sense, not completly cutting off?

I was just checking my Mppt Low temperature cut-off by setting the cutoff to 10°C and then cooling my Smart Battery Sense down below this setting.

I noticed that I was still getting 0.2A going into my battery.

Why dont I get a complete cutoff?

It was late in the day with only a little solar coming in, but I did the same the other day in bright sun and got same results but didnt record it.

As I will be charging LiFePo4 during winter and my batteries will be getting cold, I would like to know why the mppt with temperature sense is not able to completely cut off the current coming from it to the battery??
