No Lightbox in nextGEN Gallery

I would like to use nextGEN Gallery with the Customizable theme but am having an issue. When an image is clicked, it brings up the image file, not a lightbox.

Works fine if I switch themes to TwentySeventeen.
Does not work if I use my child theme or the default Customizable theme.

I find the problem seems to be in wp-content/themes/customizable/js/default.js

When I delete the following code from default.js the lightbox effect works. With the code lines in place, no lightbox, just the image file displayed directly.

Example is here: https://speterson.me/wp/small-works-i-test/

		var owl = jQuery("#owl-demo");
	 
	owl.owlCarousel({
			itemsCustom : [
			  [0, 1],
			  [450, 2],
			  [600, 2],
			  [700, 2],
			  [1000, 4],
			  [1200, 4],
			  [1400, 4],
			  [1600, 4]
			],
			itemsMobile : true,
			navigation : false,
			autoHeight : false,
	});	

Also, I can not copy default.js to my child theme and do the edit, does not work. I found that it has to be done in the original theme directory, not my child theme.

SO, two questions I guess:
Will deleting these lines cause me to have other problems?
Can anyone tell me why I can not copy default.js to my child theme folder?

THANK YOU!
