News Show Pro GK4 with K2 Categories selection

Hi,
I am using the latest version of News Show Pro GK4 for Joomla3 and in the Data source page, when I try to select K2 Categories, I am not able to scroll down the list to select all categories ( I have more than 20 categories); in other words, the scroll bar is somehow freezed;
Please help..

Hi

Please send me an access to your joomla panel.

I am doing it on my local server...
As I mentioned, the module works fine exept when it comes to select multiple categories in "Data Source", then the vertical scroll doesn't work; so impossible to select more than the visible categories..

Hi

I understand, but in order to fix it I need to see it with my own eyes, check the code with some dev tool and than propose a solution.

Please ignore this issue for now and get back to me when You will have the site online.
