Notification NORMAL status without WARNING/ALERT status.Why?

[Grandalf00]

Hi! I have Cacti 1.1.15 (1 min pooler) and 1.0.3 Thold plugin.

I make Threshold Templates with High/Low type:

Warning High -> nothing
Warning Low -> nothing
Min Trigger -> Never

Alert High -> nothing
Alert Low -> 0.1
Min Trigger -> 5 minutes

In my opinion I should get a alert notification when the data source value goes below 0.1 during ALL 5 min (in each pooler value is below 0.1).
BUT when the data source value goes below only 1, 2, 3 or 4 times in a row I should not get ANY notification. I'm right?

In my case I get a NORMAL notification every time when the data source value goes below 0.1 at least ONCE but I don't.

It's a bug in Cacti/Thold plugin or it's a normal? If it's a normal that how can I set it that I want?

Can someone help me a little?
