Cooking after cooking in moisture

Peace to the rabbi.
I’m not sure, but I heard that there are two issues in Tractate Shabbat, one of which can be understood as not cooking after cooking, and the other as cooking after cooking. Therefore, there are those who have tried to reconcile the issues that cooking after cooking is in the wet, and those who have not.
What is the Rabbi’s opinion on the matter? Is there cooking after cooking in the damp?
thanks.
