Question about Subfilter

[rsadmin]

Hello Im testing zabbix in our company to monitor switch network data.
I've installed zabbix server 6.0.25 on a ubuntu 22 system.
I noticed something about subfilters when testing Monitoring Host graphs.
If you want to see only a specific graph you can set a subfilter.

In this picture I set the subfilter so I only see data from Networkinterface 1.

But if I close this page now and open a page from another switch this happens.

The Subfilter persits through changing Hosts and now I cant see any graphs at all.

I know its possible to reset all filter with the button, but I want to use the Maps function an set links to single ports through URL feature. With this I cant reset the subfilter.
Is it possible to change the behavior of subfilters?

Click again on that subfilter, it will remove it.
But it feels like a bug, that it tries to apply filter value, that may not even exist on that selected host... I tested it on my instance here... same result, selecting a random "subfilter" and then changing host, I get first "no data to display" and active "subfilter" which is not even present on second host... clicking again, removes filter and shows all existing graphs for second host...
You can submit a report at https://support.zabbix.com/browse/ZBX and see what they answer... Is it a planned behaviour or a bug.. :P

Thnaks for this suggestion. I submited a report at https://support.zabbix.com/browse/ZBX.
I know its also possible to remove the subfilter by clicking on it.
But there is a problem with this.
I wanted to use the URL feature from Zabbix networkmap to link all Ports single graphs. So I can open all Networktraffic Graphs through my Networkmap and also set different time filters.
But this the persistent subfilter that is not possible at the moment.
