iOS music stand app service dates are wrong

On one of our iPads all the service dates are one day ahead of the correct service date. All services.
All other devices both iOS and android have the correct dates. Just this one device (iPad mini 2) wont display the correct date. I’ve looked everywhere in the app and in the system settings and can’t see anything wrong or that I can change to fix it.

Please send us a couple screenshots depicting this discrepancy as well as the email address that that iPad is signed in with.
