DNS request no longer come from Router only?

I had to reset my router to default settings and I've given my Pihole a static IP. Set it as the DNS server in LAN settings and WAN settings the same as it was originally. Now my issue is I can see different IP addresses in Client activity unlike before and I noticed a lot of DNS queries are labeled as "other DNS queries" I have the impression requests are being bypassed where they weren't before. I have been at it for hours looking for solutions and videos but nothing seems to make it operate the same as it was before. I went through everything I could in the Asus documentation too but nothing seems to change a thing. Has anyone dealt with this before? I have no clue what I'm missing.
