The "220/24" isn't treated as a netmask for automatic expansion. It is
used exactly. The only thing that generates records is the $GENERATE
directive, but even it doesn't understand "220/24" as something for
expansion.
As another poster pointed out, you don't need to delegate a /24 network
using classless delegation, but if you want to delegate a set of
addresses, say 172.20.200.0-172.20.200.63, you'd use something like
this:
(a) In 20.172.IN-ADDR.ARPA. zone:
0-63.220 NS ns-other.example.com.
$GENERATE 0-63 $.220 CNAME $.0-63.220
# which should generate:
# 0.220 CNAME 0.0-63.220.20.172.IN-ADDR.ARPA.
# 1.220 CNAME 1.0-63.220.20.172.IN-ADDR.ARPA.
# 2.220 CNAME 2.0-63.220.20.172.IN-ADDR.ARPA.
# ...
# 63.220 CNAME 63.0-63.220.20.172.IN-ADDR.ARPA.
(b) on ns-other.example.com, in 0-63.220.20.172.IN-ADDR.ARPA. zone:
0 PTR zero.example.com.
1 PTR one.example.com.
# etc.

In your config in zone 20.172.IN-ADDR.ARPA., there are no delegations
for 220/24.220.20.172.IN-ADDR.ARPA.
