Excluding fields from a Current Selections Box

[#1]

Within our application, we have several fields which are used to control navigaton and other flow within the application.  These fields have no meaning to the application user and so can be confusing if displayed,  How do we exclude these fields from the current selection box?

Here is what displays now.  The field marked with a yellow highlighter is what we wish to exclude.

This works and is IMO the best answer for my present situation.  Thanks so much
