The values of the "SSH Server" section is used when I run the job, but when i go to Configure on the job, the Transferset(s) are empty, no values in them.
When I click on Save the next time, the Transferset(s) are overwritten to be empty.

The problem is not in "Post-build Actions" the "Send built-artifacts over SSH" is able to hold the values when I go to Configure.

The problem seem to be with "Send files or execute commands over SSH" which is in the dropdown list of e.g. Build steps, Release steps.

I have attached an image where I go to Configure on my job, seeing that the values are empty.
