In template "Linux by Zabbix agent", discovery rule "Network interface discovery" (key net.if.discovery) is, in the item prototype a macro {#IFALIAS} used for tag "description".
However, the result of the discovery is:

[{"{#IFNAME}":"lo"},{"{#IFNAME}":"ens192"}]

So, in Configuration -> hosts -> items, there is a strange tag
In Monitoring -> hosts -> graphs is a strange tag
in Monitoring -> latest data is a strange tag.

We can filter on tags, and as there might be quite a few {#IFALIAS} values not resolved, we're breaking the concept there; screenshots attached.

Did not check other templates, might have the same issues.
