Hello sheriefpk and welcome to the forum.
The Report View will shor you what MAY be trapped by your trap definition but the footer (or appends) will not appear if there is/are no detail line(s) to extract.
I assume that when yuo have no detail lines you have the total but with a zero value and you need to always report that category even if there are no transactions?
If that is the case then you will need to 'see' the report in a different way. How you do that will depend on the report and whether you have Standard or Pro Monarch. Basically you need to find a way to make sure each category always has at least one line - even if the line is not really a detail line.
Can you post a short sample of the report so that we can see what is looks like and then try to identify some options for you?
