1- In a grid, turn ON "filter criteria applies to subitems".

2- Close the grid and reopen it.

3- Choose a Y/N field-column to which you'll apply a column filter criteria

4- select "non-blank"

 

You'll see that TLIs will be filtered properly but not SLIs

 

I have to turn off "Filter criteria applies to sub items", and ON again, and then everything is fine until the next grid close, reopen.

 

Anybody can confirm ?
