I am on 7.3 and I use this option a lot to ensure that my jobs are fit to be run remotely before I even deploy them to the remote server. Interestingly I have this + button enabled by default, not sure if this is a bug in the tool. I suggest to open a ticket with support, they are usually very responsive and can guide you with the issue. Nevertheless, it is a peculiar case, please post your resolution after you get a resolution to the issue.
