what is 127.0.0.1? is it your local caching server?, perhaps it is still 
caching the old info, have you done rdnc flush, or stop&start. Or maybe 
you have the zone defined on 127.0.0.1 local server with old setup? What 
I can see from here (uae) it is as you want for the forward zone 
prcdigital.com.

for reverse it is still pointing to deltacom.net. and I guess you will 
have to talk to arin to update these refferals for 133.35.66.in-addr.arpa
