Captive Portal value for hard timeout not being saved

[helixxx]

on the GUI page:
services_captiveportal.php?zone=myzone
(replace myzone with your voucher zone name) the value for hard timeout is not being saved.

WORKAROUND:
in order to change it you have to backup your config, manually edit that backup file, look for <timeout>in the <voucher>section. change it to desired value and restore backup. Restore area: ALL (restoring just the captive portal section doesn't work - this seems to be another bug)
note: once you press "save" on the voucher page it will be reset to 60 minutes!
