You need to unpublish it from the JS Job's control panel.
For example, Lets say you don't want it on the resume...
Go to Components->JS JOBS...then click on "resume" (allow it to bring down the other selections)...then "fields". Find Salary...check the box on the left side, then click "unpublish". I did a screen shot...but please don't judge...its pretty basic.
