Trigger level tag and linked templates

[hummel]

Hello,

I'm using Zabbix 5.0 on CentOS 8.3 in a setup where I'm playing with trigger tags when a template which defines a trigger is linked to another template like this:

TempA

TempB:foo

-> the foo trigger is defined in the TempB template
-> TempA has TempB in its "Linked Templates" list

In the sequential tests below, I exhibit what the Trigger Tag list shows depending on which tag I added at what "level" (i.e. on what template) :

[ Note: I'm not talking here about Inherited Tags neither Template level defined tags - only trigger tags as shown in the Trigger/Tag tab ]

1) at TempB, add the 'tempb_tag' tag to the 'foo' trigger

In TempB, foo has tempb_tag
In TempA, TempB:foo has tempb_tag

2) at TempA level, add the 'tempa_tag' tag to the TempB:foo trigger

In TempA

TempB:foo has

tempa_tag
tempb_tag

In TempB foo has tempb_tag

-> tempa_tag is not seen

3) at TempB level, add tempb_tag2

In TempB

foo has

tempb_tag
tempb_tag2

In TempA

TempB:foo has

tempb_tag
tempb_tag2

-> no more tempa_tag

Can you help me figure out why is that ? I thought 'trigger tags' were only attached to the trigger whether this trigger is "inherited" by template linking or not. But those tests seems to show otherwise and still seems to be inconsistent with any idea of template level trigger tag also.

Thanks for you help
