Resource Planner URL Share

I’m looking to utilize the Resource Planner Share Link to build a dashboard for Sr. Leadership to view resouces allocations across a Portfolio, broken out by sub groups with the Portfolio. 

For this view, I’d like to utilize the Custom column formatting and only show Available/Planned/% of Hours. Everything looks great in the Resource Management area, but when I add the Share URL to a dashboard the data doesn’t show for the custom view. Is this a known issue? Is there a fix?
