Thold 0.4.9-3, cacti 0.8.7i, PIA 3.1 issues

[xenon]

I've setup a clean install of cacti 0.8.7i with pia 3.1 for testing purposes.
I've downloaded the following plugins from http://docs.cacti.net/plugins:
plugin:settings-v0.71-1.tgz
plugin:thold-v0.4.9-3.tgz
plugin:realtime-v0.5-2.tgz

Setup and installation of plugins went smooth but it seems I've ran into several issues with thold.
I'm monitoring interface status on a cisco switch (1 up, 2 down) and created a baseline deviation threshold with the following params:
Re-alert Cycle: Never
Time range: 1 Day
BD UP: 25
BD DOWN: 25
Trigger Count: 1
Alert list: Admin (contains only 1 email address)

When I shutdown a port on the switch the threshold triggers an alert and an email is correctly sent. Then come the issues:
1. Although re-alerting is set to Never, after 5 minutes pass I still receive an Alert that the value is still above the calculated threshold. (Workaround: setting the re-alerting cycle to 1 Month)
2. When I bring the port up again there is no e-mail sent to notify me that the value restored to normal. (Couldn't find any workaround for this one.)

I'll be glad to provide any details necessary to fix those issues Thanks!

for the realert issue see if the thold table in MySQL shows a 0 in the column "repeat_alert"

for the missing normal email: was the threshold in breach state (not warning) long enough to trigger an email and a breach status on the webpage?
