Source translations are showed correctly as of 1.3.0-rc5. Destination NAT needs verification.

As requested, checked in 1.3.0-rc and it shows the destination translations with basic configuration.

Configuration:

set interfaces ethernet eth1 address '10.2.0.15/24'
set nat destination rule 10 destination address '30.30.30.2'
set nat destination rule 10 inbound-interface 'eth1'
set nat destination rule 10 log
set nat destination rule 10 translation address '10.2.0.15'

Testing:

vyos@vyos6# run sh nat destination translations
