I think the parameter may be involved in both calculation of the worksheet. what I could suggest is in your summary worksheet, don't apply the parameter in your calculation, or if the calculation is the same one, probably duplicate the calculation and get rid of the parameter from the duplicated one and apply to your summary worksheet.
Parameters in Tableau are static values set by the user that are global - i.e. are constant across the entire workbook until manually changed by the user - -
so you can use them in the formulas or filters where you want to use them - they can be used in multiple formulas or multiple filter - you don't need to apply the filter all sheets -
