You attached a workbook but it was a twb that does not include the data - please attach a TWBX workbook that includes the data
As Jim said, it's difficult to answer this without a packaged workbook (twbx), but my guess is that a single date can have multiple IDs? If so, then you'll just get an asterisk if you try to put that on your tooltip. The alternative would be to create a new sheet which lists the IDs, then leverage viz-in-tooltip. See the following for how to use viz-in-tooltip: https://interworks.com/blog/hcalder/2018/06/04/mastering-viz-in-tooltip-and-tooltip-filtering-in-tableau/
