Hello,
I am playing around with the Plan view in Jira software for the first time and am noticing that the view is not including all expected work items in its views and charts.
I am using a filter as the work source for my Plan; this filter returns 716 work items, but in the Work Item source page of plan settings, shows as only returning 332 work items.
Filter view:

Work item source view:

I have the same permissions levels for all projects/work items in the filter, so I cannot fathom why this is happening and it is making all of the charts and analysis, which would otherwise be incredibly helpful, meaningless.
Does anyone have any suggestions? Thanks!
