Double gfci on my hot tub

I inherited a Catalina SPA hot tub with an Acura Powerstation control that contains an internal high current GFCI. These are the GFCI with a donut in the back normally used to switch a relay contactor. I recently ran 220v/50A service to the hot tub and installed a disconnect box close to it that includes a 50A GFCI. The Powerstation GFCI went bad and I would prefer not to replace it and bypass directly to the main contactor. My question: Since I already have a 50A GFCI installed in the disconnect box, do I need to have the internal one located in the SPA control as well? What would be the risk of bypassing it (removing it)? Help is appreciated.
