I have the same issue before, please check the following details:

Not working code sample:

Intent notificationIntent = new Intent("~~~.BaseActivity");
        notificationIntent.putExtra("type", 2);
        notificationIntent.putExtra("appName", "testApp");
        notificationIntent.putExtra("messageEN", "Good evening");
        notificationIntent.putExtra("notificaitonID", 4);


        PendingIntent broadcast = PendingIntent.getBroadcast(context, 4,
                notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.HOUR_OF_DAY, 18);
        calendar.set(Calendar.MINUTE, 10);
        calendar.set(Calendar.SECOND, 0);
        // this is to show it at the 6:10 

        AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);



        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
                    calendar.getTimeInMillis(),
                    AlarmManager.INTERVAL_DAY,
                    broadcast);

Working Code:

    Intent notificationIntent = new Intent("~~~.BaseActivity");
    notificationIntent.putExtra("type", 2);
    notificationIntent.putExtra("appName", "testApp");
    notificationIntent.putExtra("messageEN", "Good evening");
    notificationIntent.putExtra("notificaitonID", 4);


    PendingIntent broadcast = PendingIntent.getBroadcast(context, 4,
            notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    Calendar calendar = Calendar.getInstance();
    calendar.set(Calendar.HOUR_OF_DAY, 18);
    calendar.set(Calendar.MINUTE, 10);
    calendar.set(Calendar.SECOND, 0);
    // this is to show it at the 6:10 

    AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);


    Calendar nowCalendar = Calendar.getInstance();

    if (calendar.after(nowCalendar)) {
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
                calendar.getTimeInMillis(),
                AlarmManager.INTERVAL_DAY,
                broadcast);

    } else {
        calendar.add(Calendar.DAY_OF_MONTH, 1);
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
                calendar.getTimeInMillis(),
                AlarmManager.INTERVAL_DAY,
                broadcast);
    }

it's done only when you about to set the repeating, you need to check if it's passed or not, and if it's passed just add the wanted time for repeating
