EDNS (ECS) problem

I run the CLI on an ASUS router and always saw my ECS info I went to dnscheck.tools, but for the past few weeks the ECS info is missing.  I have removed and reinstalled the CLI, reset the router and tried different browsers but cant figure out what's going on.  If I use the NextDNS app or the profile directly on my devices the ECS info does come through, only the router CLI seems to have an issue.
