How to deal with the drift in water in the 412-660 band after Rayleigh scattering of GOCI by using Seadas-ocsSW's l2gen?

How to solve the problem of drift in the water body of the lake in the 412-660 band after Rayleigh scattering of GOCI by using Seadas-ocsSW's l2gen to generate rhos products? Or what caused it?

The rayleigh correction done by l2gen is different for land and water pixels. If the geolocation of the sensor is off by a bit then you will see a difference on land/water interfaces.
