Help S Planner Notifications

[Stuntman]

I'm having an issue with S Planner. I would change the notification sound, but then after some time, it seems to always change back to the default notification sound. Anyone else having this issue?

I'm using an I747-M model on Bell.

The phone will not let me disable this app. I tried to just use Google Calendar, but if I remove the calendars from S Planner, they are also removed from Calendar.

It seems to revert back to the default sounds and notification settings after restarting the phone.
