In some CP patch design the polarization changes for LHCP to RHCP, What should be the possible reasons?

I have designed a dual print dual cp antenna, identical patch on both side of the substrate (placed side by side), on analysis, it is found it is showing LHCP in one band and RHCP in another band....
