Hiding Columns by tick


In a view under a wizard, I want to hide columns by clicking “Columns” button as in the picture below. I used MDX cross join for columns and I inserted row using insert column feature of Apliqo. However, when I click “Columns” button, there are no any item on the list.

*Red arrows points at inserted row

What might be the cause? Is there anybody experiencing that before ?

If there are two identical columns created by an MDX, then all columns disappear in “Columns” list.
