Portfolio Element – setting items and columns count

Hello.

I’m having problems with the portfolio element.
I created a page and insert the element of the portfolio page builder. I set the element portfolio to display 5 columns per row. The problem that is happening is that the 10 items of portfolio that have registered only 9 are displayed.
