empty zones and higher zone count after upgrading

[Con Wieland]

I upgraded on of our servers from  9.6-ESV-R8 to 9.8.5-P2 and I am showing 66 more zones than I had before. 

I now have:

< ; Zone dump of '64.100.IN-ADDR.ARPA/IN/internal'
< ;
< ; not implemented

thru

< ; Zone dump of '127.100.IN-ADDR.ARPA/IN/internal'
< ;
< ; not implemented

when I do an rndc dumpdb -zones


I do not have any xxx.100.IN-ADDR.ARPA zones configured. And these do not show up as empty zones that get created from the documentation I found

any ideas would be greatly appreciated
