Hi there, @dallasbrews.
I'd be glad to help display all your active items only when running your custom summary report.
I just wanted to clarify, did you open the Custom Summary report or the Item QuickReport? Either way, you have the option to customize the report by selecting the filter choices.
It's also important to consider the filtered date of the report. The inactive items will show if you filtered the date wherein the transactions have those items. If you need to hide these, make sure to unchecked the Show inactive inventory items on the filter choices.
Let me know if this is not what you're referring to. You can also check this article if you need details about customizing item reports: Customize item reports.
I'm here to help you further if you have additional questions about the Custom Summary report. Have a good one.
