That's a glitch that happens to a lot of people at the end of their second season. Unfortunately, I haven't heard of any solutions for the problem yet. A lot of people on 2ksports.com have said that it's because you have to start a brand new My Player file after updating with the official patch or else the glitches won't go away (clone glitch, hanging at end of 2nd season etc.), so if you didn't do that, it's probably what's wrong. Either way, I think you have to start again unfortunately. Unless someone on here has a solution, or you can Google it
