If you only have one settlement agreement, the settlement agreement has the effect of a contract. If there is any dispute over the contents of the contract, both parties can settle it through consultation, and you can negotiate with the plaintiff to modify the settlement agreement.

If the conciliation statement issued by the court is mandatory, in this case, the court may be required to correct the conciliation statement.

My opinion: this situation should be solved as soon as possible, and whoever should be consulted should be consulted. Don't be careless
