Something is wrong as you dont have two network interfaces "eth0" & "eth0:0".
Instead you somehow managed to squeeze two IP addresses on one interface "eth0".
Whats in:
cat /etc/network/interfaces
And whats in:
tail -10 /etc/dhcpcd.conf
pi@raspberrypi:~ $ cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'
# Include files from /etc/network/interfaces.d:

iface eth0:0 inet static

pi@raspberrypi:~ $ tail -10 /etc/dhcpcd.conf

Sorry, I was mistaken, the "ip addr show" command is displaying the interfaces properly.
Am prepping some changed instructions but in meantime, whats output of below:
sudo netstat -nltup | grep 'Proto\|lighttpd\|nginx\|dnsmasq\|dhcpcd\|pihole-FTL'
please dont apologise!
it should be me apologising!

Helped out via WebEx.
Turned out that the static IP addresses in the "intrerfaces" file are assigned before the ones in the "dhcpcd.conf" file.
Leaving dnsmasq to think the one in the "intrerfaces" file (the alias interface) to be the primary one and the one in the "dhcpcd.conf" file (physical interface) to be the secondary.
Only fix I could think of was move all the static IP address assignments from "dhcpcd.conf" into the "intrerfaces" file.
Tried other way around but no go as dhcpcd5 didnt work on the alias interface.
Stupid dhcpcd5
