increase the amount of posts in the news show pro slideshow?

Hi there, I am trying to increase the amount of posts being featured in the news show pro widget here on the homepage: http://www.jamjosandbox.com/mag/ from 3 to 6. Right now it only shows 3 and I want it to show 6 but it will not increase. Which setting do I change for this. Thanks in advance.

I think I figured this out - you need to set the cache to 0 in the widget to see the changes. However is there a way to clear cache without having to set it to nothing in the Advanced setting of the widget itself?

If you set cache to 0 - it's disabled, so there's no need to clear it later, I'm not sure if I understand your question.

Well you I change the widgets alot sometimes and need to flush the cache and I am not sure if I need to go into each widget individually and then set the cache to 0 and then back to 60mins again if I need to flush it or not?

but when you are changing the widget settings and save the widget, the cache is cleared automatically.

Oh ok, for some reason the cache was not clearing for me until I changed the widget to 0mins on the cache. Il test again and let you know.
