Dynamic date table for filtering whole report

Hi,

I have a report with 4 different tables.  I want to be able to filter the whole report off of one date slicer because each table has a different date field that I'm using for said chart, card, etc.  I couldn't get it to work so I restarted my report with the dynamic date table called "Dates" and a table called "Leads Entered"

Here is example data:

Leads Entered:

Dates:

My goal is to use the Date column in the Dates table to filter the whole report, but I can't get this to work.

This is the relationship that I setup (a many to one)

Then when I go to my report to create the date slicer / card, no data populates:

All of my data in this table is in August of 2019.

Thanks! Not sure what I'm doing wrong.  If this doesn't make sense, I'd be more then happy to provide more screenshots / info.
