Hi,
tldr; here is a short video showing the issue :
Better quality:
Configuration
I have created a simple smart folder :
In the folder a kanban view
I select “hide empty rows” here:
And I see properly my cards:
I then select “hide empty columns” from the filter
Which works on the current selected entity
Now the problems
I select another entity: I see empty rows and columns (not OK)
I go back to the filters and uncheck / recheck “hide empty row” “hide empty columns”
Now I see nothing in the board (which is OK)
I got back to the previous entity and see nothing in the board (not OK)
Workaround : I can uncheck/recheck again.
