Competition menu glitch

If you play up to 6 competitions or try a 7th. Game gives you a message that you can’t do anymore competitions and need to delete some. You get stuck on competition menu to choose to delete a competition. It will not let you delete and Pressing “O“ button won’t exit or go back to main menu and I had to close game by pressing PS4 button to close window on PS4 menu for RC4. I restarted game and then got back to competition menu to delete some comps. I was able to do so. It appears the glitch occurs when you try to start a 7th competition. You just can’t do anything or delete anything or exit. PS4.
