I have pi-hole currently running on my Raspberry Pi 4 B. The problem I'm facing is that I have a few Local DNS records saved [using the Web GUI], and every single DNS query results in correct IP address. But querying it using ping sentinel.local (sentinel.local is what I have set for the Raspberry Pi) doesn't work. at. all.
[ everything below this line is about the Pi on which I have pi-hole running ]
Pi-hole version is v5.3.1 (Latest: v5.3.1)
AdminLTE version is v5.5 (Latest: v5.5)
FTL version is v5.8.1 (Latest: v5.8.1)

nslookup works...
nslookup sentinel.local

Non-authoritative answer:

dig works too...
dig sentinel.local

but ping doesn't

Why does nslookup and dig work but ping doesn't? I did make a Git issue previously, but it turned out it wasn't a pi-hole problem. Don't want to harass the dev with my own issue [again].
I did have 10.0.0.14 network wide, but do not use it currently
