Gotcha. Corrected.
Kind of. I guess there were no recent queries (as in: within the last 100 queries Pi-hole received) queries made by this client. It's the same as in Query log shows less than 100 entries when only blocked/permitted queries are shown · Issue #2535 · pi-hole/AdminLTE · GitHub
But there is a real cosmetic bug: "blocked" is doubled within the header
Well, there were queries. It's just neither client=10.66.66.62 nor client=aliasclient-0 returns a null table. However, query log has retained all logs of DNS requests made by client iphone i.e. 10.66.66.62.
