If you have 2 orders then you probably need to go to the judge and get clarification. Present the evidence of completion and ask for the original schedule to be implemented. You do not want to think you are doing the right thing and it backfire.
If the fiance is the reason for the negative impact with the kids and you are fighting a losing battle, get rid of him. To me he would not be worth the threat of losing the kids. You are not married yet and apparently he did accost you at one time...
