After a cost model has been loaded, it is calculated immediately according to the state of the current drawing. If you have made changes to the cost model or to the active drawing — for example, if you have drawn a new object in the Cutting style that affects the TotalRules parameter in the cost model — you need to recalculate the cost model to ensure that the changes are taken into account.
IMPORTANT: When you recalculate a cost model, input parameters do not change their values unless you edit them explicitly.

IMPORTANT: To save the calculated data, make sure you have make sure you have set a location where the parameter value modifications that you make during your work will be saved. Setting such a location allows you to use your modified data the next time you open the project.
