Trigger overview behavior when using the built-in templates

I'm experiencing inconsistent behavior with trigger overview whenever I'm using the built-in host templates.

One of examples:

 1 Windows 10 host, with a proc.num[notepad.exe] item and a {Windows:proc.num[notepad.exe].last()}=0 trigger expression. this works fine and is being displayed on the trigger overview page as described.

Now, if I add one of the built-in templates, for example - "Template Module ICMP Ping" the trigger overview is starting to behave erratically.

In the given example, whenever I close the notepad process, only "notepad process" trigger is being displayed in the trigger overview. (screenshot)

However, when I open the notepad process on the host and the problem is resolved, I'm seeing the "notepad process" trigger and the ICMP ping related triggers from the template - which, from my understanding, should be the intended behavior (see screenshot). I'm experiencing similar behavior when using other templates (ex. Template OS Windows)
