I am conducting a simulation for a spinning golf ball flying through the air. The MRF method was utilized where there are 2 zone a stationary (rectangle) zone and a rotating (circular zone). My golf ball diameter is 42.6mm and the rotating zone diameter is 50 mm. When initializing the solution in Fluent I got an error saying, Info: Interface zones, 11 and 12, possibly penetrate each other. This could adversely affect your solution. Zone 11 is the contact region trc and zone 12 is the rotating zone contact region trg. How do I solve this issue?

Yes, I can see the problem. Plot the two sides of the nonconformal and you'll see the issue.
