Shipping Charge is Automatically Calculated as £5.99 though I set it as £5

Hi,

I already set up a profile on shipping in the settings.

In the shipping profile I gave for Orders over £60 Free, for Orders less than £60 it is £5.00.

But, in the checkout the shipping charge is appearing as £5.99. I am not sure where it is coming from.

Though the profile says, if order is above £60 then it is free, the system makes it free if it is above £50.

I am doing this test on the Partner Site.

Thanks,
