@jeevith Thanks for reaching out to us!
I can see the concern here but the behaviour of our Manage-Assets Pack is correct.
There are only Deploy & Delete actions which are supported.
Deploy : Creates the assets if not already created over the orchestrator if they exists , it will override the value with the current value provided in the csv.
Delete : Deletes the assets.
This is what we have mentioned here in our official docs as well.
I can see there is a discrepancy in the hover info( i.e. we don’t have any explicit Update action neither it is expected to be selected.) ,we have taken a note of this will be correcting this in our upcoming release.
