Is there any link between duplex kidneys and addisons disease?

I recently found out I have two duplex kidneys while trying to find a diagnosis for the illness I have been expiriencing. I also found out my cortisol levels are very low which have prompted my doctors to send me for more testing, possibly for addison's disease.

I am wondering as both these conditions are very rare and very few people have a duplex kidney, let alone two, could the dual exit from both my kidneys be affecting my adrenogland and therefore my cortisol levels? Does anyone know if there is a connection between duplex kidneys and low cortisol or addison's?
