Rolling days not showing correcting on appointment field of RT PCR test form

I have entered 30 rolling days for test but calendar only shows 7 days, anyway to change that? Not sure what else I can change

On your form, you have set up the rolling days as 7 on your appointment field:

The appointment field above this one is hidden on the form and it shows 30 days as rolling days.

Please check and let us know.
