I run my own DNS servers at home (the ones below). I noticed this setting was getting DNS info from my ISP. I manually set them as my own two DNS servers. Could this cause any adverse affects? Thanks.

Only adverse effect is if your DNS server is down at home, so is everything else. I stopped using my home DNS server as my primary for this reason.
 
If you're using my firmware, make sure you also enable the option that tells the router to forward local queries to upstream DNS servers - that way the router will be able to use your internal DNS for LAN resolution.

(sorry, can't check the exact name of the setting, I don't have access to a router at the moment).
 
"Forward local domain queries to upstream DNS"

i have my own dns server as well.

it is set as my dns in the lan side of the asus merlin page.

if i do aas the OP and set up wan dns to point to the internal dns as well.... and agree to foward local queries to this dns server as it is the upstream...

what happens is webpages dont resolve.

and i get this via nslookup

C:\Users\loacpc>nslookup espn.com
