How to delete a cloud sync backup job

I set up a single sync job to see how it works -- went fine.
Now the job tries to run itself every day--I change the schedule to "not scheduled" bu t that wont save with the job. No way to delete the job definition--it tries to run every day--dont need it, dont like to keep stuff in the cloud.

I get "certification server is unavailable. Try again later" and it wants me to connect a hard-cable to the internet (what?) this thing is online wireless.

anyway, I want to delete this job definition--but the option to delete is "grayed out" and so I cant delete it.

HOW do I delete this job definition?

thanks in advance
eric
