Crystal Reports 2013: Formula field will not display on page

[Former Member]

I have a formula called PickOutstanding. Here is the code:

if OnLastRecord and {@Calc} < 0 THEN 
    toText({@shipctns}-{#RTotal0}) & " Outstanding" 

which works on the report but does not show. For example: In the first image is my report, with where @PickOutstanding is highlighted

@PickOutstanding does not show. However when I click into it:

It clearly is showing right there. What could be causing it to be hidden on the report itself and how do I get it to show?

Full images in case it is difficult to see the difference between pictures
