i have 1 oc300 and 3 oc200 . .all of them behave the same. when selecting 1 or 2 voucher groups then clicking EXPORT to xls format.. they export the entire voucher groups. not only the selected ones. Now its worth to mention that i have 2 sites in cloud based controllers, they are working fine when you select one voucher group then export it, it will only generate the one selected not the entire voucher groups in the controller,
