Problem with 'rflux' and 'ntflux_acc' in surface to surface radiation

I was trying to analyse a 2D state state model of surface-to-surface heat exchange between two concentric cylinders. The temperature at OD of the inner cylinder and the temperature at the ID of the outer cylinder is specified. However, when I compare the integral of 'rflux' and 'ntflux_acc' on any of these boundaries, these values are different.
If I understand right, the total heat transferred to the surface by radiation must be equal to the total heat transfer by conduction, so why are the two integrals different?
