Unable to add caption(description) for gallery with new nextgen gallery plugin

I just updated the plugin for my gallery that used to have the title and description under each thumbnail.

I updated to nextgen plugin 2.1.7 and now the description wont show. The page that has the gallery listed has it listed as [nggallery id=40 template=caption]. The template under settings has the caption one selected. The plugin editor does not have a have a next gen caption plug in. The php file looks like this (so I have no idea where I’d edit it to incorporate a caption):
if ($this->is_pro_incompatible()) {
$pro_modules = array(
‘photocrati-comments’,
‘photocrati-galleria’,
‘photocrati-nextgen_pro_slideshow’,
‘photocrati-nextgen_pro_horizontal_filmstrip’,
‘photocrati-nextgen_pro_thumbnail_grid’,
‘photocrati-nextgen_pro_blog_gallery’,
‘photocrati-nextgen_pro_film’,
‘photocrati-nextgen_pro_masonry’,
‘photocrati-nextgen_pro_albums’,
‘photocrati-nextgen_pro_lightbox’,
‘photocrati-nextgen_pro_lightbox_legacy’,
‘photocrati-nextgen_pro_ecommerce’,
‘photocrati-paypal_express_checkout’,
‘photocrati-paypal_standard’,
‘photocrati-stripe’
);
foreach ($pro_modules as $mod) $this->_registry->blacklist_module_file($mod);
}

I have been reading several forums but can’t find one a) isn’t something I haven’t tried 2) doesn’t apply to me/confusing.

Can someone please help in lay terms?? Thank you so much!
