Creating a Filter Control on a Calculated Field Breaks Filter Control
There's an issue that I've seen across multiple reports I've created in Google Data Studio.
As a very basic example let's say that you have a date field, and you create a calculated Field to extract the Day of the week (Monday, Tuesday, etc.)
If you create a filter control on that Day of the week Field, the checkboxes will not work correctly:
Notice what happens if you click on ONLY next to one of these values in the filter control. All the checkboxes disappear:
It should preserve the checkbox next to the value that you choose ONLY on. This allows the user to know what value has been selected with the control.
I am able to reproduce this issue on various dashboards where I use the filter control on calculated fields.
