Yeah. There is a fundamental issue with this setting caused by how Pi-hole evolved over time. It's the reason why this setting is due for deprecation for some time and will finally go away without replacement in Pi-hole v6. There is just no need to do this these days.

Thanks for your report. This is a bug, I can reproduce it. It's tied to your setting AAAA_QUERY_ANALYSIS=no in pihole-FTL.conf.
While this should not influence query analysis and handling (only reporting), it seems it does. (See https://docs.pi-hole.net/ftldns/configfile/#aaaa_query_analysis).

Moving this to the FTL realm.

It's this part

FTL/src/dnsmasq_interface.c

Lines 577 to 583 in d201776

	// Skip AAAA queries if user doesn't want to have them analyzed
	if(!config.analyze_AAAA && querytype == TYPE_AAAA)
	{
	if(config.debug & DEBUG_QUERIES)
	logg("Not analyzing AAAA query");
	return false;
	}

Thanks for the explanation. As a short term solution setting 'AAAA_QUERY_ANALYSIS=yes' is used to have Pi-hole block the AAAA requests as well.
