Sorry for the delay on this. I looked in to the issue and confirmed it was related to an earlier bug that is fixed in the beta version of the app. The beta has been out since December 2016 so I promoted it to production. If you update your Mooshimeter app in a few hours you should be updated to 1.0.34 and the issue should be resolved.
Sorry again for the delay, let me know if the issue persists. Thanks!
