Time Calculation Rule Ignores Payroll Time Types on Time Card

Summary

How can I make sure the rule only works on Overtime Time Type

Hi, 

I have a Time Calculation Rule, that when the Payroll Time Type of 'Overtime' is selected on the Time Card certain calculations can be added - for instance if the person is Part Time an additional payment is made or if it is on a weekend a premium is added. If only Overtime is claimed on the Time Card it works perfectly.

If another Payroll Time Type is claimed on the Time Card then the rule is not called into action and no premiums are paid. Although Both elements are paid correctly.
