Steps to reproduce:

1. Check queues overview and overview by proxy in administration tab.
2. Check latest data from "Queue over 10 minutes" items (zabbix[queue,10m]) for Proxies and Server.
3. Compare three data sets.

Result:
See screenshots. Data from overviews is normall, while values from zabbix[queue,10m] item for proxies are overvalued, like it holds something in cache. Values for Zabbix server are ok. Proxies have set "Monitored by: <itself>" in config tab.

Issue occurs on different proxy/server versions: 6.4.1, 7.0.0, 7.0.2.
Expected:
Item values should match Queue overview data.
