Steps to reproduce:

Hello I have a little problem with grafana and zabbix, I'm trying to make a basic dashboard on grafana to display information on a host via SNMP, so for info, the connection with the zabbix server and the host did not cause any problems, the connection between my zabbix server and my grafana server either, I can retrieve metrics from my zabbix server from grafana, but I do not understand why I do not have access to all the data from grafana.
in my lastest data when I filter to see info that has the tag application:synology disk.

I see info, but since the grafana, it tells me no data when I ask it to display all the info that has this tag.

whereas if I take the application:cpu tag (for example), I see data in last data

and I have the same information in grafana and zabbix, which seems normal to me, given that the zabbix plugins for grafan are supposed to retrieve it.

Expected:
Just to be able to retrieve all the data via the API (and not just what the API is willing to take), to be able to display them on grafana, I thought the problem was only linked to data that aren't numerical values, but no, some numerical data doesn't come up either (temperatures for example).
