Hey @Jaivik333 and @Jaivik333, Alex here!
This is usually caused because a transaction has been done mid-cycle (this also includes new activation). No worries, though, the application will re-synchronize itself at the start of your next cycle and you'll be able to see your usage details again.
If this isn't the case for you, you can get in touch with our customer service here and they'll be able to look into what might be causing this.
Hope this helps!
