Yes, you should first try adding a Safe State Machine assignment in the Assignment Editor.  That will ensure your SM can't get into one of the many illegal states possible with one-hot encoding.  But you also should be coding your next state logic properly.  Can you show in your code how you're defining states and the next-state logic?
