Reminders appearing for not active Calendars

I use more than one Calender (Work/Private) with different sub calendars on two accounts (Mcrosost Exchange and 365).

Even if the "work" calendar is "not selected" to appear (still sync is on), all the meeting reminders (alarms) are occuring for it. This makes no sense, as I just want to get them for the selected once (private). So either it should be fixed, or there should be a option like "allow alarms for active calendars".
