Implementation of boundary conditons at liquid-liquid interface

I am simulating a liquid-liquid flow in a channel. The liquid-liquid interface appears to be curved as one phase liquid is dispersed as droplets. I have used the laminar flow single phase interface for each fluid since the interface is not deformed. The boundary stress node was used to specify the normal and tangential stress balances on the interface, in which the general stress for one fluid was set to be euqal to the other fluid taking into account of pressure jump caused by surface tension. I got converged velocity profile in each fluid, but to find the stress balances were not satisified in the obtained results. I have no clue on what's wrong with my boundary condtions.
Anyone would like to shed some light on that? Thanks.
