Job grade filter on internal job postings under Current jobs

Content

We are creating requisitions using positions with no template attached to positions. While creating a requisition, we do not select the grade field and it is hidden. I am still able to see the job grade filter on the current jobs pages. Does it automatically come from the job that position is attached to? Should the job grade filter be displayed if we are creating requisitions using positions and not selecting grade field while creating a requisition?

Any insights on this would be helpful.
