# 10 wire is not rated for 50 amp breaker. You should buy a new 30 amp gfi and install in main panel. Ground and neutral should only bonded together at first point of disconnect
The OP is using a circuit with 30 amp overprotection at the main panel. The 50 amp GFCI is just providing ground fault protection, no current overprotection.
