For two counters it makes no difference but note that you can combine
named counters with maps:

map voipcounters {
 type ipv4_addr . inet_service : counter
 elements = { 10.0.1.1 . 5160 : "voip1", 10.2.1.1 . 5161 : ...

and then count with one rule only:

counter name ip saddr . udp dport map @voipcounters

Can't repro so looks like this is already fixed.

> tables mangle and nat should not be printed (still have them separately from converting iptables to nft)...in json-format it is right

Yes, they should not be printed.
