Schedule task reminder problems in add-in 'Task Control for bpm’online'

When I am in my section with process, in this case Lead, and attempt to schedule a Task with the schedule task -button.

The Start-time I choose is one week from now. However the reminder-time is initially set to the current date and time. 2019-04-05 09:28. (The reminder time is set to one week ahead of the start time, which seems strange).

Another strange thing that happens is that when i uncheck and re-check the Reminders > Responsible check-box. The Reminder date and time changes to the vales of the Activitys Start time, date and time.

Update : The issue described above only exists when I have the add-in Task Control for bpm’online (https://marketplace.bpmonline.com/app/task-control-bpmonline) installed.
