Hi Rohin,
Thanks for getting in touch, I appreciate your patience.
In the deployment preview section, we show the machines that each step will execute on.
The Deploy Release
step doesn’t execute on machines (as it runs on the Octopus Server) so it doesn’t show the target machines.
Whereas the Deploy Package
step does execute on machines, so it will display each of the machines it’s going to run on.
This has been discussed in the following issue found here; I’d recommend having a look here for a breakdown.
A UserVoice suggestion (which is mentioned in the associated ticket) can be found below; I’d recommend leaving your vote and thoughts for this.
I hope this helps!
If you require any further assistance or clarification, please let me know
Kind Regards,
Reece
