Show/Hide column in Table List

Hi,
I've some problems with show/hide fields on LIST page functionality.
I'm using PHPRUNNER Enterprise (Build 36520 x64), and I would like to open a LIST TABLE (20 fields total) with few columns displayed;
after that I would decide to show/hide field with the check-box selection from the total list of field (show/hide fields selector).

That's what I get:

1. Every time I load the page, ALL the fields are displayed, even if I selected (let me say) only 4 fields in the LIST PAGE SETTINGS
2. If I want to hide a column, first I must check and then uncheck the field from the list
3. Once I get the wanted list, if I apply a filter, or even just reload the page, I get the full column list again

Thanks in advance for your feedback
