Take a look at the methodology behind the buildout of the canvas column below. By building out with the parent row and using formulas, you should not get the duplication of the views anymore.
Go into the settings of your row and you can set up “all tasks embedded” to be viewed as a table when you edit the layout inside the row. To do this all you need to do is press the three dots in a vertical line at the top of the layout editor, then select the column, and toggle the “table” button.
The Tasks Table can live in a hidden page or somewhere in the database and hidden. But the big thing is that you are not creating a bunch of different views, you are only affecting the one table now.
