Apply Dynamic Loading in block configuration does not stick

This does not seem to work for me.
I've created a view named arts_tab with Page type Dynamic Full Node with 1 node per page, and with Block type Dynamic Teaser List 5 nodes per block with more. And then I have placed the block Dynamic: arts_tab in main content area and checked Apply Dynamic Loading in the block configuration, but when I go to the View page, i see the full node of the first node followed by the teaser list. If I click one of the teaser titles, it reloads but after that clicking the titles does not do anything.

When I go back and look at the Block configuration, I see that the Apply Dynamic Loading is no longer checked. I think this setting is not sticking.

I have turned off that block for the time being so you cannot look at that live, but here is my exported view:

$view = new stdClass();
$view->name = 'arts_tabs';
$view->description = 'term: artstab';
$view->access = array (

$view->view_args_php = '';

$view->page_title = 'arts_tabs';
$view->page_header = '';
$view->page_header_format = '1';
$view->page_footer = '';
$view->page_footer_format = '1';
$view->page_empty = '';

array (

);
$view->exposed_filter = array (

$views[$view->name] = $view;
