Doesnt work at all without internet

Freeletics itself is the best but since 1 week the app doesnt save workouts without Internet connection and updates really really slow.it automatically gives 2 repititions instead of 1even if you select 1 repitition,please solve it sooner because it takes out all fun and feeling of achievement.thanks
